A well respected wild life researcher recently conducted a
study of wild Jackalopes. He trapped and weighed 60 adult
wild Jackalopes in an attempt to gauge their health. As a
population, if a species loses weight it could be a signal
that the health of the population is in danger. Research conducted 10 years prior found that the population mean was 69.9 pounds. Test the claim that population mean of wild Jackalopes is equal to 69.9 lbs. Use a significance level of .01.
Claim: ______________
Null Hypothesis: ________
Alternative Hypothesis: ___________________________
Test Statistic: (state the statistic and find it’s value):
Find the pvalue for the given test statistic:
At the 0.01 significance level would you reject the null or fail to reject the null? Justify your answer.
What final conclusion could you draw from your research?
Answers
Answer:
Claim : men weigh of wild jackalopes is 69.9
The null hypothesis : H0 : μ = 69.9
Alternative hypothesis : H1 : μ ≠ 69.9
Test statistic = −2.447085
P value = 0.0174
Conclusion :
Fail to Reject the Null hypothesis
Step-by-step explanation:
From the question given :
The claim is that : mean weight of wild jackalopes is still the same as 10 years with a mean weight of 69.9 lbs.
The null hypothesis : H0 : μ = 69.9
Alternative hypothesis : H1 : μ ≠ 69.9
Using calculator :
Sample mean (x) = 66
Sample standard deviation (s) = 12.345
The test statistic t :
(x - μ) / (s/√n)
n = sample size = 60
(66 - 69.9) / (12.345 / √60)
t = −2.447085
P value at α 0.01, df = 59 is 0.0174
Since the p value is > 0.01, the result is not significant at 0.01. Therefore, we fail to reject the Null

In Mrs. Wilson's math class the ratio of girls to total students is 5 to 8. if there are 24 total students, how many boys are in the class?Can you do step by step please
Answers
Answer:
9
Step-by-step explanation:
Your ratio is 5 to 8
We know the total people in the class is 24 students. the total of the ratio (8) times 3 gives us 24! So, we also multiply the 5 by 3, which gives us 15. But its asking how many girls. If there are 15 girls, the rest are boys. So we subtract 24 by 15, which gives us 9

Function f(x) represents the population of bacteria x hours after 9 a.m. What does F(2)-F(1) represent?
Answers
Answer:
f(2)-f(1) => Difference between the count of bacteria between 11AM and 10AM
Step-by-step explanation:
Here x is the number of hours after 9AM
f(2) means the count of bacteria after 2 hours of 9AM i.e. at 11AM
f(1) means the count of bacteria after 1 hour of 9AM i.e. at 10 AM
f(2) - f(1) will give us the difference between the count of bacteria between 11 AM and 10 AM
Hence,
f(2)-f(1) => Difference between the count of bacteria between 11AM and 10AM

A college student goes to lunch at school and pays for lunch with her ID. Her mother put money into her account for her to do so, but she doesn’t know how much. Lunch is the same cost each day , but she doesn’t know what the cost is. After buying 4 lunches, she sees that her account balance is $91 . After buying 9 lunches , her balance is $67.25 .
Answers
Each lunch would cost 4.75
Yes, the relationship is linear.
The cost of each lunch is $2.639.
The initial amount deposited by her mother is $101.55.
What is the slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is
y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.
From the data itself, we can obtain two points to find the slope the points are
(4, 91) and (9, 67.25).
Slope(m) = (67.25 - 91)/(9 - 4).
Slope(m) = - 2.639.
The cost of each lunch is 2.639.
∴ 67.25 = -(2.639).9 + b.
b = 91.
∴ y = -(2.639)x + 91.
The initial amount put by her mother is 91 + 4(2.639) = $101.55

PLEASE help me!!! I need help with this problem below.... what is the rule for the sequence 1.8, 2.85, 3.90, 4.95, 6 Please answer this with a clear step by step explanation before tomorrow And help me out! Thanks!
Answers
Answer:
The next term is equal to the previous term with an added 1.05.
Step-by-step explanation:
The given sequence is:
1.8, 2.85, 3.90, 4.95, 6
The first term is:
[tex]a = 1.8[/tex]
The second term is:
[tex]a_2 = 2.85[/tex]
The third term is:
[tex]a_3 = 3.90[/tex]
The fourth term is:
[tex]a_4 = 4.95[/tex]
The fifth term is:
[tex]a_5 = 6[/tex]
Let us have a look at the difference of each term:
Second term - First term = 1.05
Third term - Second term = 1.05
Fourth term - Third term = 1.05
Fifth term - Fourth term = 1.05
We can see that there is a common difference between each term of the given sequence.
Therefore, we can conclude that:
The given sequence is an Arithmetic Progression which has the difference of each term as equal.
First term, [tex]a = 1.8[/tex]
Common difference, [tex]d =1.05[/tex]
So, the rule is:
The next term is equal to the previous term with an added 1.05.
A stack of 10 different cards are shuffled and spread out face down. If 3 cards are turned face up, how many different 3-card combinations are possible?
Answers
Answer:
120 different waysStep-by-step explanation:
Using the combination formula as shown;
nCr = n!/(n-r)!r!
If a stack of 10 different cards are shuffled and spread out face down. If 3 cards are turned face up, the number of different ways 3cards combinations are possible is expressed as;
10C3 = 10!/(10-3)!3!
10C3 = 10!/(7)!3!
10C3 = 10*9*8*7!/7!*3*2
10C3 = 10*9*8/3*2
10C3 = 720/6
10C3 = 120 different ways
Hence there are 120 different card combinations
The different 3-card combinations that are possible are; 120 possible combinations
This is a combination probability problem with the formula;
nCr = n!/((n-r)!r!)
Where;
n is sample size
r is possible choice
In this case;
n = 10
r = 3
Thus;
The different 3-card combinations possible are;
10C3 = 10!/((10 - 3)!3!)
>> 10!/(7! × 3!)
>> 120
Thus,there are 120 possible combinations of 3 different cards.
