**Step-by-step explanation:**

Hello!

The null hypothesis is the commonly accepted fact, if you were to make an experiment, you'll state in the null hypothesis what is already known of your population, another way to see it is that the null hypothesis has the "no change" statement. When doing a statistic test you seek to nullify the null hypothesis to replace it with the alternative hypothesis, i.e., the objective of any hypothesis test is to invalidate this hypothesis not to prove the alternative hypothesis right.

In short words, you work to annulate what is accepted knowledge and not to prove what you think happens.

I hope it helps!

**Answer:**

Therefore, we conclude that the statement in **(A)** is incorrect.

**Step-by-step explanation:**

We have the following sentences:

A) If the probability of an event occurring is 1.5, then it is certain that event will occur.

B) If the probability of an event occurring is 0, then it is impossible for that event to occur.

We know that the range of probability of an event occurring is in the segment [0, 1]. In statement under (A), we have the probability that is equal to 1.5.

Therefore, we conclude that the statement in **(A)** is incorrect.

Answer:

(a) less than 10 minutes

= 0.5

(b) between 5 and 10 minutes

= 0.5

Step-by-step explanation:

We solve the above question using z score formula. We given a random number of samples, z score formula :

z-score is z = (x-μ)/ Standard error where

x is the raw score

μ is the population mean

Standard error : σ/√n

σ is the population standard deviation

n = number of samples

(a) less than 10 minutes

x = 10 μ = 10, σ = 2 n = 50

z = 10 - 10/2/√50

z = 0 / 0.2828427125

z = 0

Using the z table to find the probability

P(z ≤ 0) = P(z < 0) = P(x = 10)

= 0.5

Therefore, the probability that the average waiting time waiting in line for this sample is less than 10 minutes = 0.5

(b) between 5 and 10 minutes

i) For 5 minutes

x = 5 μ = 10, σ = 2 n = 50

z = 5 - 10/2/√50

z = -5 / 0.2828427125

= -17.67767

P-value from Z-Table:

P(x<5) = 0

Using the z table to find the probability

P(z ≤ 0) = P(z = -17.67767) = P(x = 5)

= 0

ii) For 10 minutes

x = 10 μ = 10, σ = 2 n = 50

z = 10 - 10/2/√50

z = 0 / 0.2828427125

z = 0

Using the z table to find the probability

P(z ≤ 0) = P(z < 0) = P(x = 10)

= 0.5

Hence, the probability that the average waiting time waiting in line for this sample is between 5 and 10 minutes is

P(x = 10) - P(x = 5)

= 0.5 - 0

= 0.5

**Answer:**

The width of the fence measures 6 feet

Step-by-step explanation:

Firstly, we assign variables.

Let the width of the fence be represented by w and the length by l

Now let’s get what the length would be. width is 2 less than half length

w = l/2 - 2

or simply l/2 = w + 2

which is same as l = 2(w + 2)

Now the perimeter of the fencing is 44. The perimeter of a rectangle can be calculated using the formula

P = 2(l + w)

Now let’s insert what we have:

P = 44 and l = 2(w + 2)

44 = 2(2(w+2) + w)

44 = 2(2w + 4 + w)

44 = 2(3w + 4)

44 = 6w + 8

6w = 44-8

6w = 36

w = 36/6

w = 6 feet

**Step-by-step explanation:**

the **width** of the fence is 6 feet. Let's denote the length of the rectangular fence as "L" and the width as "W." According to the problem, we have two pieces of **information**:

1. The total **length** of fencing available is 44 feet, which means the perimeter of the **rectangle** (the sum of all sides) should be 44 feet. The formula for the perimeter (P) of a rectangle is P = 2L + 2W.

2. The width is two less than half the length, which can be written as: W = (1/2)L - 2.

Now, we can set up an **equation** using this information and solve for the values of L and W:

First, we have the **perimeter** equation:

2L + 2W = 44

Now, we can substitute the **expression** for W from the second piece of information:

2L + 2((1/2)L - 2) = 44

Now, simplify and solve for L:

2L + (L - 4) = 44

Combine like terms:

3L - 4 = 44

Add 4 to both sides:

3L = 48

Now, divide by 3:

L = 48 / 3

L = 16

Now that we've found the length (L), we can find the width (W) using the second piece of information:

W = (1/2)L - 2

W = (1/2)(16) - 2

W = 8 - 2

W = 6

So, the width of the fence is 6 feet.

How many dollars of Fran's weekly pay is spent on books and clothing?

O

A. $25

OC. $50

O D. $100

OB. $30

**Answer:**

C. $50

**Step-by-step explanation:**

She spends 10% of her pay on books and 15% on clothing, for a total of 25% on books and clothing.

0.25 × $200 = $50

**Fran spends $50 of her pay on books and clothing**.
