#32). Both photos are the same equation.

H:?
Determine if this test is left-tailed, right-tailed, or two-tailed.
O left-tailed
O two-tailed
O right-tailed
Should the standard normal (z) distribution or Student's (t) distribution be used for this test?
O The Student's t distribution should be used
O The standard normal (z) distribution should be used
Determine the test statistic for the hypothesis test. Round the solution to four decimal places.
Determine the p-value (range) for the hypothesis test.
Op-value < 0.0005
O0.0005 < p-value < 0.005
O0.005 < p-value < 0.01
O 0.01 < p-value < 0.025
O 0.025 < p-value < 0.05
O 0.05 < p-value < 0.10
Op-value > 0.10
Determine the appropriate conclusion for this hypothesis test.
O The sample data do not provide sufficient evidence to reject the alternative hypothesis that the
average range of this electric car is less than 222 miles and thus we conclude that the true range of
this electric car is likely less than 222 miles.
O The sample data provide sufficient evidence to reject the alternative hypothesis that the average
range of this electric car is less than 222 miles and thus we conclude that the true range of this
electric car is likely 222 miles.
O The sample data do not provide sufficient evidence to reject the null hypothesis that the average
range of this electric car is 222 miles and thus we conclude that the true range of the electric car is
likely 222 miles.
O The sample data provide sufficient evidence to reject the null hypothesis that the average range of
this electric car is 222 miles and thus we conclude that the true range of the electric car is likely lesS
than 222 miles.

Transcribed Image Text:Electric vehicles are often categorized by the range of miles that can be travelled on a single battery charge, since charging stations are not yet widespread in the United States. The latest model of a certain brand of electric car is reported to have an average range of 222 miles. An auto industry journalist would like to verify this claim, since she believes that the true range of the car may be less than 222 miles. The journalist selected and tested a random sample of 143 cars of this model and found that the average range of the sample was 211.9 miles with a standard deviation of 35.8 miles. Apply the p-value method to test the hypothesis that the average range of this electric car model is less than 222 miles, using a = 0.005. State the null and alternative hypothesis for this test. Ho: ? v H: ? v Determine if this test is left-tailed, right-tailed, or two-tailed. O left-tailed O two-tailed O right-tailed Should the standard normal (2) distribution or Student's (t) distribution be used for this test?
