Answer:

a

 i. Proportion

b

 Best point estimate is   [tex]\^ p = 0.60[/tex]

c

   [tex]z_{\frac{\alpha }{2} } =  2.58 [/tex]

d

   [tex]E =  0.0206 [/tex]

e

   [tex] 0.5794 <  p < 0.6206 [/tex]    

Step-by-step explanation:

From the question we are told that

   The sample size is  n = 3765

   The  proportion that feel the businesses in Laradise, are run by compliant individuals  is  [tex]\^ p = 0.60[/tex]

Considering question a

   The correct option is  Proportion  because in the prompt we are told to obtain the fraction of the total sample size that has a particular attribute (which their opinion of business in Laradise) and this is what a proportion represents

Considering question b

  The best point estimate is   [tex]\^ p = 0.60[/tex] because this proportion best defines the fraction of the sample size who feel the businesses in Laradise, are run by compliant individuals

Considering question c

  Generally given that the sample size is large enough n > 30 , it then means that the distribution is approximately normal  so  

From the question we are told the confidence level is  99% , hence the level of significance is    

      [tex]\alpha = (100 - 99 ) \%[/tex]

=>   [tex]\alpha = 0.01[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]z_{\frac{\alpha }{2} } =  2.58 [/tex]

Considering question d

Generally the margin of error is mathematically represented as  

     [tex]E =  Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]

=>  [tex]E =  2.58 * \sqrt{\frac{ 0.60  (1- 0.60 )}{ 3765} } [/tex]

=>  [tex]E =  0.0206 [/tex]      

Considering question e

Generally 99% confidence interval is mathematically represented as  

      [tex]\^ p -E <  p <  \^ p +E[/tex]

=>   [tex] 0.60  -0.0206 <  p < 0.60  + 0.0206[/tex]    

=>   [tex] 0.5794 <  p < 0.6206 [/tex]    

Answer:

1/25

Step-by-step explanation:

45 meters is equal to 4500cm

4500 divide by 180 is 25

So, 180 is equal to one over 25

(One twenty-fifth)

Answer:

a

[tex]P(29.81 < X < 35) = 0.21141[/tex]

b

[tex]P( X > 35) =0.28859[/tex]

c

 [tex]P( X < 20) =0.14601[/tex]    

Step-by-step explanation:

From the question we are told that

    The mean is  [tex]\mu = \$29.81[/tex]

    The standard deviation is [tex]\sigma = \$9.31[/tex]

Generally the probability that the hourly pay of a randomly selected flight attendant  Is between the mean and $35.00 per hour is mathematically represented as

      [tex]P(29.81 < X < 35) = P( \frac{ 29.81 - 29.81 }{9.31} < \frac{x - \mu }{\sigma} < \frac{ 35 - 29.81 }{9.31} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

     [tex]P(29.81 < X < 35) = P( 0 < Z < 0.5575 )[/tex]

=>   [tex]P(29.81 < X < 35) = P( Z < 0.5575) - P( Z < 0)[/tex]

From the z table  the area under the normal curve to the left corresponding to  0 and  0.5575   is  

   [tex]P( Z < 0) =0.5[/tex]

and

   [tex]P( Z < 0.5575) = 0.71141[/tex]

=>   [tex]P(29.81 < X < 35) = 0.71141 - 0.5[/tex]

=>   [tex]P(29.81 < X < 35) = 0.21141[/tex]

Generally the probability that the hourly pay of a randomly selected flight attendant  Is more than $35.00 per hour is mathematically represented as

   [tex]P(X > 35) = P( \frac{x - \mu }{\sigma} > \frac{ 35 - 29.81 }{9.31} )[/tex]

   [tex]P( X > 35) = P( Z > 0.5575 )[/tex]

From the z table  the area under the normal curve to the right  corresponding to 0.5575   is  

    [tex]P( Z > 0.5575 ) = 0.28859[/tex]

=>  [tex]P( X > 35) =0.28859[/tex]

Generally the probability that the hourly pay of a randomly selected flight attendant Is less than $20.00 per hour is mathematically represented as

   [tex]P(X <20 ) = P( \frac{x - \mu }{\sigma} < \frac{20 - 29.81 }{9.31} )[/tex]

   [tex]P( X < 20) = P( Z < -1.0537 )[/tex]

From the z table  the area under the normal curve to the right  corresponding to -1.0537  is  

    [tex]P( Z < -1.0537 ) = 0.14601[/tex]

=>  [tex]P( X < 20) =0.14601[/tex]

Answer & Step-by-step explanation: 4.58

PEMDAS:

Parenthesis first! (8 + 7 + 3.3) = 18.3

Exponents second! [tex]1/2^{2}[/tex] = 1/4 = 0.25

Multiply third and solve! 18.3 x 0.25 = 4.575

Round if needed! 4.575 = 4.58 = 4.6 = 5

Answer:

25

Step-by-step explanation:

The first step in simplifying the expression of the square root of 50 involves finding factors of 50. This just means we are trying to find two whole numbers that, when multiplied, equal 50. Since 50 is an even number, 2 is going to be a factor, and so we can rewrite 50 as 2 times 25.

Answer:

The answer is 6

Step-by-step explanation:

12 divided by 2 is 6. If you have a fraction of 1/2, then its half of it. 6 is half of 12. :)

Answer: 6

Explanation:

You can multiply the numerator by the numerator and the denominator by the denominator.

The numerator of 12 is 12 and denominator of 12 is 1.

[tex]\frac{12}{1} *\frac{1}{2}=\frac{12}{2}[/tex]

Simplify this fraction and you get 6 over 1 or just 6.

You can also use common sense (not really).

You probably know that 1/2 is one half. To find half of something, you would normally divide by 2. 12 divided by 2 is 6.

Step-by-step explanation:

Step-by-step explanation:

take away the decimal point for it

Answer:

Arranging the terms from least to greatest:

[tex]\frac{3039}{1000}<\frac{3200}{1000}<\frac{3990}{1000}<\frac{8200}{1000}[/tex]

Now actual terms arranged from least to greatest will be:

[tex]3\frac{39}{1000}<3\frac{1}{5} <3\frac{99}{100}<3\frac{52}{10}[/tex]

Step-by-step explanation:

We need to arrange the weights [tex]3\frac{1}{5} ,3\frac{39}{1000},3\frac{99}{100},3\frac{52}{10}[/tex] from least to greatest.

To arrange them in least to greatest we need to convert them into improper fractions and then make their denominators same.

[tex]3\frac{1}{5}=\frac{16}{5} \\3\frac{39}{1000}=\frac{3039}{1000} \\3\frac{99}{100}=\frac{399}{100} \\3\frac{52}{10}=\frac{82}{10}[/tex]

Now, Making their denominator same by taking LCM of 5,1000,100 and 10

The LCM is 1000

Now the fractions will become:

[tex]\frac{16}{5}=\frac{16*200}{5*200}=\frac{3200}{1000}[/tex]

[tex]\frac{399}{100}=\frac{399*10}{100*10}=\frac{3990}{1000}[/tex]

[tex]\frac{82}{10}=\frac{82*100}{10*100}=\frac{8200}{1000}[/tex]

Now we have fractions: [tex]\frac{3200}{1000},\frac{3990}{1000},\frac{8200}{1000},\frac{3039}{1000}[/tex]

Now the smallest term will be one having smallest numerator

Arranging the terms from least to greatest:

[tex]\frac{3039}{1000}<\frac{3200}{1000}<\frac{3990}{1000}<\frac{8200}{1000}[/tex]

Now actual terms arranged from least to greatest will be:

[tex]3\frac{39}{1000}<3\frac{1}{5} <3\frac{99}{100}<3\frac{52}{10}[/tex]
