The commercial for a new pizza store claims that it takes 15 minutes for them to make a pizza. An advocate thinks that the production time is different from 15 minutes.

The advocate surveyed 11 randomly selected people who purchased a pizza from the pizza store and found that their average time was 15.5 minutes. The standard deviation for this survey group was 3.6 minutes.

Based on this data, they calculated the test statistic to be 0.461 and the p-value to be 0.655.

What can be concluded at the = 0.001 level of significance?

With this, the final conclusion is that

  • A) The data suggest that the population mean amount of time to make a pizza at Super Fast Pizza is not significantly different from 15 at = 0.001, so there is statistically insignificant evidence to conclude that the population mean amount of time to make a pizza at Super Fast Pizza is different from 15
  • B) The data suggest the population mean is not significantly different from 15 at = 0.001, so there is statistically insignificant evidence to conclude that the population mean amount of time to make a pizza at Super Fast Pizza is equal to 15.
  • C) The data suggest the population mean is significantly different from 15 at = 0.001, so there is statistically significant evidence to conclude that the population mean amount of time to make a pizza at Super Fast Pizza is different from 15.
