Question
For steps 3 and 7, only one row is applicable, as it states. The green boxes are supposed to be rounded to 4 decimals and the blue are 2 or 3 depending on whether a Z or T table is appropriate
The U.S. Department of Transportation provides the number of miles that residents of the 75 largest metropolitan areas travel per day in a car. Suppose a random sample of 41 Buffalo residents and 28 Boston residents yielded the following results. (See exercise 12 on page 449 of your textbook for a similar problem.) Buffalo E xbar = xbar = 18.9 Question 2A Based on the data, can you say the mean number of miles Boston residents travel per day is less than the mean number of miles Buffalo residents do at a=0.025? State the hypothesis in terms of Boston-Buffalo. Step 1: HO: Ha: Step 2: Step 3: Fill in row 88 if the hypothesis is one tailed. Reject HO if Fill in row 92 if the hypothesis is two tailed. The smaller number must be typed first. Reject HO if Step 4: Step 5: Step 6: Step 7: Fill in row 102 if the z table is appropriate. P-value Fill in row 106 if the t table is appropriate. The lower boundary must go on the left and the upper boundary on the right. P-valueExplanation / Answer
Reject H0 if test statistics is greater than 2.0003
test statistics = 1.9319
Failed to reject H0
p-value = 0.029
