pg. You suspect that the mpg is more for your car. The 43 trips on the highway that you took averaged 33.3 mpg. At the α = 5% significance level of significance, use the 4-step hypothesis testing to test if the mean of your new car is more than 32 mpg. Does the manufacturer meet their claim at 5% significance level? (1) State the null and alternate hypothesis H0: …………………………; Ha: ………………………. (2) Determine the test statistic, round to two decimal places (3) Determine the p – value. Graph the situation. Label the test statistic and the P-value on the graph. Round your answer to three decimal places (4) At the 5% significance level, determine if the manufacturer meets their claim. Explain your answer in relation to the context.
The manufacturer claims that your new car gets 32 mpg on the highway with the standard deviation 5.5
mpg. You suspect that the mpg is more for your car. The 43 trips on the highway that you took averaged
33.3 mpg.
At the α = 5% significance level of significance, use the 4-step hypothesis testing to test if the
your new car is more than 32 mpg.
Does the manufacturer meet their claim at 5% significance level?
(1) State the null and alternate hypothesis
H0: …………………………; Ha: ……………………….
(2) Determine the test statistic, round to two decimal places
(3) Determine the p – value. Graph the situation. Label the test statistic and the P-value on the graph.
Round your answer to three decimal places
(4) At the 5% significance level, determine if the manufacturer meets their claim. Explain your answer in
relation to the context.
