Pollsters just report the results of hypothesis tests that show statistical significance but not those in which there was insufficient evidence.
Find out coefficient of correlation between variables. Interpret the value.
The Speedy Oil Change Company advertised a 15-minute wait for an oil change. A sample of 23 oil changes showed a mean time of 16.5 minutes and a standard deviation of 4.3 minutes.
Which 56 have this coverage. Does this support the claim that the proportion is less than 15%? Test the claim at the 5% level by the following steps.
Calculate the test statistic for testing the null hypothesis. The slass mean will be not be signfically different from the population mean. What is your decision about the null hypothesis?"
Perform a test to determine whether there is sufficient evidence to support a claim of a linear correlation between two variables. Find the critical values of r given the number of pairs of data n and the significance level alpha.
At the .05 significance level, can we conclude that the mean waiting time is less than 3 minutes?
