In the US, the average one-way commuting time is 26.4 minutes. Is this different in Atlanta? One survey of 35 Atlanta commuters found an average one-way commuting time of 30.7 minutes. (a) The test statistic is 1.1846. What is the meaning of this test statistic? The average error between different sample results and the hypothesized mean is 1.1846.The current sample result is 1.1846 standard errors above the hypothesized mean. The maximum error between different sample results and the hypothesized mean is 1.1846. (b) Based on the test statistic of 1.1846, what is the p-value to test if the average commuting time in Atlanta is different than the rest of the US? (4 decimals.) (c) On the basis of the above p-value, what can be said regarding a 95% confidence interval for the true average commuting time? The interval contain the value 26.4, because this value .

A survey found that the mean commute time is 25.4 minutes for the fifteen largest U.S. cities.The Austin, TX, chamber of commerce feels that Austin's commute time is less. A survey of 25 randomly selected commuters had a mean of 22.1 minutes with a standard deviation of 5.3minutes. At the 10% level, does the survey data suggest that Austin commute time is significantly less than the national average?Your answer should have the following: 1). Significance Level: Alpha =2).
