A. Conduct a hypothesis test to determine whether the mean miles traveled last month equals 10,000. Use the .01 significance level. Find the p-value and explain what it means H1: u not Ho: =100 (Test the hypothesis that the mean miles different from 10,000 at 1%) Miles T-Statistic: #REF! P-Value 0.0001 Mean 11120.43 Sample Siz 80 Standard E 68.85433 Mean #REF! Median 11195 Stan. Dev. Err:504 Mode 11698 Significant 0.01 Standard [ 615.8518 Sample Va 379273.5 Explanation: The p-value in this problem is less than .01 which is .0001, so Kurtosis -1.21921 the null hypothesis is rejected at 1% level of significance. There is sufficient evidence to indicate that the mean miles traveled last month differed from Skewness -0.308563 10,000.

A study of school bus fleets reports that the b. average per bus maintenance cost is $4,000 per year. Usi cost variable, conduct a hypothesis test to determine whether the mean maintenance cost for Lincolnville than $4,000 at the .05 significance level. Determine the p-value and report the results
