Answer:

a. committed a type 1 error

Step-by-step explanation:

The correct option is - a. committed a type 1 error

Reason -

Type 1 error occurs  when a true null Hypothesis is rejected

Type 2 error occurs when a false null Hypothesis is accepted

Now,

Let us state that,

The null hypothesis and alternate hypothesis is

H0 : There is no difference between the mean lifetimes of the new and old designs

H1 : There is a difference between the mean lifetimes of the new and old designs

Now,

As there is no difference between the mean lifetimes of the new and old designs.

⇒ The null hypothesis is true.

But p value suggests that null hypothesis should be rejected

∴

We have committed a Type 1 error that is rejecting a true null hypothesis.

So,

The correct option is - a. committed a type 1 error

Answer:

The durations of movies in minutes can only take on integer values from 0 to 60. Therefore, it is a discrete data.

The time spent watching a movie is an example of Continuous function.

We gather information to look for connections, patterns, and other ideas. For instance, if you keep track of how many push-ups you perform every day for a month, your overarching objective is to assess your development and rate of advancement. For example heart beat rate, signal, etc.

Numerical information that is continuously referred to the undefined variety of measurements that might be taken across two realistic sites. For example - time, wind, temperature, pressure, etc.

Despite the fact that these numbers are often gathered via accurate measurements, they are also not necessarily neat and orderly as those in categorical data.

Answer:

66/150

Step-by-step explanation:

So the question asks the probabilty for buttons.

so we see that 23 has buttons so we discard for now,

35 has no buttons but a zip so we acknowledge it

49 has no buttons and no zips so we keep it too.

now we do 35+49 which is 84.

since there is 150 bags and 84 of those bags dont have buttons, the rest must do.

150-84=66

so there are 66 bags with buttons so we put this in a fraction -> 66/150

Tangent (non necessary for the question persay):

since we cant simplify you keep it as 66/150. If you are doing this on mathswatch, then remeber if there is a question like this next and you can simplify, simplify.

for this question it is not necessary.

The probability that the bag is selected at random have buttons is 11/25.

Probability is the chance of happning an event among all the events possible. It lies between 0 and 1. It is calculated by dividing number of items by total number of items.

We have been given that company makes 150 bags out of which 23 of the bags have buttons but no zips and we have to calculate the probability that a bag chosen at random have buttons.

35 of the bags have zips but no buttons.49 of the bags have neither zips nor buttons.so we see that 23 has buttons so we discard for now, 35 has no buttons but a zip so we can say that it that 49 has no buttons and no zips so we keep it too.now we do 35+49 which is 84. Because there are  150 bags and 84 of those bags dont have buttons, the rest must do.

150-84=66, we got that there are 66 bags with buttons so we put this in a fraction= 66/150.

Probability=66/150

Hence the probability of getting a bag that has buttons is 66/150.

Answer:

a) There are 93,367,432,000,000 ways to place the lunch order.

b) There are 11,861,676,000,000 ways for the company to place the lunch order if the 10 lunches purchased are all different.

Step-by-step explanation:

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

a. How many different ways are there for the company to place the lunch order for the 10 lunches?

For each of the 10 lunches, there are 25 options. So

[tex]25^10 = 93,367,432,000,000[/tex]

There are 93,367,432,000,000 ways to place the lunch order.

b. How many ways are there for the company to place the lunch order if the 10 lunches purchased are all different?

The order is important, which means that the permutations formula is used to solve this question. So

[tex]P_{(25,10)} = \frac{25!}{(25-10)!} = 11,861,676,000,000[/tex]

There are 11,861,676,000,000 ways for the company to place the lunch order if the 10 lunches purchased are all different.

Answer:

each apple would be $1.53

Answer:

$1.53 per pound of apple

Step-by-step explanation:

I'm assuming the question is what is the cost of 1 pound

Set up a equation:

3pounds/$4.59 = 1pound/x

Variable x = cost for one pound

3/4.59 = 1/x

Cross mulitply

3 × x = 4.59 × 1

3x = 4.59

Divide both sides by 3

3x ÷ 3 = 4.59 ÷ 3

x = 1.53
