Yoooo how do you do this?!

Answer:

there is insufficient evidence to support the claim that more than 10% of the employees are paid minimum wage.

Step-by-step explanation:

Given that:

A marketing organization claims that more than 10% of its employees are paid minimum wage.

The null hypothesis is:

$H_o : p = 10$

The alternative hypothesis is:

$H_1 : p > 10$

If a hypothesis test is performed that fails to reject the null hypothesis, how would this decision be interpreted

i.e Decision Rule: fails to reject the null hypothesis

Then the interpretation of the decision is that, there is insufficient evidence to support the claim that more than 10% of the employees are paid minimum wage.

A sample of n = 10 automobiles was selected, and each was subjected to a 5-mph crash test. Denoting a car with no visible damage

solmaris [256]

Answer:

a) From definition the proportion of successes would be:

$\hat p = \frac{x}{n} = \frac{7}{7+3}= 0.7$

b) Data : 1,1,0,0,1,1,1,0,1,1

x = 7 for this case

$\hat p = \frac{7}{10}=0.7$

The proportion in part (a) is exactly equal to the mean in part (b)

c) We have actually 7 successes and 3 fails and we want this condition:

$\frac{x}{n}=0.6$

The new value of n would be 25 so then we can solve for x and we got:

$x = 25*0.6= 15$

So we need 15 successes and we have 7 so then we need $15-7 = 8$ successes in the new 15 cars in order to satisfy the condition.

Step-by-step explanation:

Data: S S F F S S S F S S

S means success and F damage. We have 7 successes and 3 damages for this case

(a) What is the value of the sample proportion of successes x/n?(

From definition the proportion of successes would be:

$\hat p = \frac{x}{n} = \frac{7}{7+3}= 0.7$

(b) Replace each S with a 1 and each F with a 0. Then calculate x for this numerically coded sample.How does x compare with x/n?

Data : 1,1,0,0,1,1,1,0,1,1

x = 7 for this case

$\hat p = \frac{7}{10}=0.7$

The proportion in part (a) is exactly equal to the mean in part (b)

(c) Suppose it is decided to include 15 more cars in the experiment. How many of these would have to be S's to give x/n = 0.6 for the entire sample of 25 cars?

We have actually 7 successes and 3 fails and we want this condition:

$\frac{x}{n}=0.6$

The new value of n would be 25 so then we can solve for x and we got:

$x = 25*0.6= 15$

So we need 15 successes and we have 7 so then we need $15-7 = 8$ successes in the new 15 cars in order to satisfy the condition.
