In a study of the accuracy of fast food​ drive-through orders, one restaurant had 36 orders that were not accurate among 324 ord
tia_tia [17]

Answer:

We do not have sufficient evidence to reject the claim that ,the rate of inaccurate orders is equal to​ 10%.

Step-by-step explanation:

We want to use a 0.01 significance level to test the claim that the rate of inaccurate orders is equal to​ 10%.

We set up our hypothesis to get:

H_0:p=0.10------->null hypothesis

H_1:p\ne0.10------>alternate hypothesis

This means that: p_0=0.10

Also, we have that, one restaurant had 36 orders that were not accurate among 324 orders observed.

This implies that: \hat p=\frac{36}{324}=0.11

The test statistics is given by:

z=\frac{\hat p-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }

We substitute to obtain:

z=\frac{0.11-0.1}{\sqrt{\frac{0.1(1-0.1)}{324} } }

This simplifies to:

z=0.6

We need to calculate our p-value.

P(z>0.6)=0.2743

Since this is a two tailed test, we multiply the probability by:

The p-value is 2(0.2723)=0.5486

Since the significance level is less than the p-value, we fail to reject the null hypothesis.

We do not have sufficient evidence to reject the claim that ,the rate of inaccurate orders is equal to​ 10%.

Grace is trying to read a story many books as she can this summer. Her father promised to give her a quarter for every book she
amm1812
Her father will owe her $10.50 because you have to multiply .25 (The amount of a quarter) and 17 which will give you $4.25. Once you do that you have to multiply .25 and 25 to give you $6.25 and when you add those together you get $10.50
