An automobile manufacturer claims that their jeep has a 36.5 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the MPG for this jeep. After testing 13 jeeps they found a mean MPG of 36.8 with a standard deviation of 2.3. Is there sufficient evidence at the 0.05 level that the jeeps outperform the manufacturer's MPG rating? Assume the population distribution is approximately normal. Step 1 of 5: State the null and alternative hypotheses. E Keypad Keyboard Shortcut Answer 田 Tables !! Họ: Ha:

The summary statistics for a certain set of points are: n= 25, s, = 107.27, E (x-x)´ = 70.93, and b, = 39.37. Use the critical value method to test the null hypothesis H,: B, =0 versus H, : B, >0. Use the a = 0.01 level of significance. Part: 0/ 4 Part 1 of 4 Find the critical value(s). Round the answer to three decimal places. If there is more than one critical value, separate them with commas. Critical value(s):

NT #2 You wish to test if the proportion of adults in a small town who are fully vaccinated differs from 55%. You select a random sample of 258 adults in this town and find that 120 of them are fully vaccinated. Set up an appropriate hypothesis test, calculate the p-value and state your conclusion. Use a significance level of a = .01.

Using the P-value method decide if you should reject the null hypothesis or not. In a sample of 81 adults selected randomly from one town, it is found that 8 of them have been exposed to a particular strain of the flu. At the 0.01 level of significance, you wish to test the proportion of all adults in the town that have been exposed to this strain of the flu is 8%
