Hypothesis tests for a mean
Instructions. Specify the Sample size. Specify the shape of the distribution, Normal or Right skewed. Specify the Mean. Specify the null value being tested for the mean or Null mean. Specify the Alternative for the test. Select Update applet to reload the applet. A new Hypothesis tests for a mean result was created.
StatCrunch
In addition to a hypothesis test, StatCrunch can also create a confidence interval for the population mean. For this example, in the window containing the hypothesis test results above, choose Options > Edit to reopen the dialog window. Under Perform, choose Confidence interval for μ.Be default StatCrunch has a value of 0.95 for the Level input which will produce a 95% confidence level for ...

PDF Sta 213: Statcrunch Guide Ii
We hypothesized that the true mean distance is 15. Our p-value indicates that, if the true mean is 15 , the probability of observing a sample mean of 15.9757 or higher (or - two-sided - 14.0243 or lower) is 0.059. Since this p-value is larger than our significance level 0.05, we fail to reject the null hypothesis that the true mean is 15.

In addition to a hypothesis test, StatCrunch can also create a confidence interval for the population mean. For this example, in the window containing the hypothesis test results above, choose Options > Edit to reopen the dialog window. Under Perform, choose Confidence interval for μ.By default StatCrunch has a value of 0.95 for the Level input which will produce a 95% confidence level for ...
Hypothesis Test for Mean Difference using StatCrunch
The phrase "Can the engineer support the claim…" tells me this is to be a hypothesis test. The second part of that sentence, "have different mean braking distances" indicates it is a test of the difference in means, µ d = µ 1 - µ 2. That phrase also tells me the claim is "the means are different" which says the population ...
