An advocacy group claims that the mean braking distance of a certain type of tire is 75 feet when the car is going 40 miles per hour. In a test of 45 of these tires, the braking distance has a mean of 76 and a standard deviation of 5.9 feet. Find the standardized test statistic and the corresponding p-value.

z-test statistic = 1.14, p-value = 0.2555

z-test statistic = 1.14, p-value = 0.1278

z-test statistic = -1.14, p-value = 0.1278

z-test statistic = -1.14, p-value = 0.2555

The heights of 82 roller coasters have a mean of 284.9 feet and a standard deviation of 59.3 feet. Find the standardized tests statistics and the corresponding p-value when the claim is that roller coasters are less than 290 feet tall.

z-test statistic = -0.78, p-value = 0.4361

z-test statistic = 0.78, p-value = 0.2192

z-test statistic = -0.78, p-value = 0.2192

z-test statistic = 0.78, p-value = 0.4361

Assuming the population is normally distributed, test the claim that the mean is more than 23 using an of 0.05.The sample statistics are a mean of 24.9, standard deviation of 2.11, and an n of 9.

The data support the claim, as the null was rejected and the claim is the alternative.

The data support the claim, as the null was not rejected and the claim is the null.

The data do not support the claim, as the null was not rejected and the claim is the null.

The data do not support the claim, as the null was rejected and the claim is the alternative.

A company claims that the hold times for customer service averages at most 10 minutes.A random sample of 24 hold times has a mean of 11.2 minutes with a standard deviation of 7.2 minutes.Is there enough evidence to support the claim at = 0.05?Assume the population is normally distributed.

No, since p of 0.211 is greater than 0.05, fail to reject the null. Claim is alternative, so is not supported

No, since p of 0.211 is greater than 0.05, reject the null. Claim is null, so is not supported

Yes, since p of 0.211 is greater than 0.05, fail to reject the null. Claim is null, so is supported

Yes, since p of 0.211 is less than 0.05, reject the null. Claim is null, so is supported

A coach claims that all players can run more than 1.5 miles.A random sample of 17 players finds that they can run an average of 1.8 miles with a standard deviation of 0.41 miles.Is there enough evidence to support the claim at of 0.01? Assume the population is normally distributed.

No, since p of 0.004 is greater than 0.01, fail to reject the null. Claim is null, so is not supported

Yes, since p of 0.004 is less than 0.01, reject the null. Claim is alternative, so is supported

Yes, since p of 0.004 is less than 0.01, reject the null. Claim is null, so is supported

No, since p of 0.004 is greater than 0.01, reject the null. Claim is alternative, so is not supported
