The following steps explain how to do a Hypothesis Test.

  • Step 1: Specify the Null Hypothesis. ...
  • Step 2: Specify the Alternative Hypothesis. ...
  • Step 3: Set the Significance Level α
  • Step 4: Calculate the Test Statistic and Corresponding P-Value. ...
  • Step 5 If the P-Value < α
  • We reject the null hypothesis

Let us assume that a dealer claims the gas mileage of a specific model of a car is greater than 25 miles per gallon.

What is the null and alternative hypothesis?

If you decide your level of confidence is 0.9 and the p value is 0.05 what is your decision?

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Test the claim that the mean lifetime of car engines of a particular type is greater than 220,000 miles. Sample data are summarized as n = 23, ?̅ = 226,450 miles, and s = 11,500 miles. Use a significance level of ? = 0.01.

An automobile manufacturer has given its car a 31.131.1 miles/gallon (MPG) rating. An independent testing firm has been contracted to test the actual MPG for this car since it is believed that the car performs over the manufacturer's MPG rating. After testing 110110 cars, they found a mean MPG of 31.331.3. Assume the population variance is known to be 3.613.61. Is there sufficient evidence at the 0.10.1 level to support the testing firm's claim? Step 1 of 6: State the...

In a random sample of 36 three-star hotel rooms in Chicago, the mean room rate is $163 with a standard deviation of $41. At α=0.10, what type of test is this and can you support the analyst’s claim using the p-value? Claim is the alternative, fail to reject the null as p-value (0.054) is less than alpha (0.10),...

A credit reporting agency claims that the mean credit card debt in a town is greater than $3500. A random sample of the credit card debt of 20 residents in that town has a mean credit card debt of $3619 and a standard deviation of $391. At α=0.10, can the credit agency’s claim be supported? Yes, since p-value of 0.19 is greater than 0.10, fail to reject the null. Claim is null, so is supported No, since p-value of 0.09...

1.) Choose the true statement. a.) If a null hypothesis is rejected for a test statistic at the α=0.05 level, then at the α=0.01 level it would never reject. b.) If a null hypothesis is rejected for a test statistic at the α=0.05 level, then at the α=0.01 level it would always reject. c.) If a null hypothesis is rejected for a test statistic at the α=0.05 level, then at the α=0.01 level it may or may not reject. 2.)...
