melissa's null hypothesis is that the average calories in frozen mac n cheese is 350 (that is, the population average is 350). since she only has one sample, she uses the bootstrap to estimate the average and ultimately decides to create a confidence interval. she also chooses an 8% p-value cutoff. what kind of confidence interval should she use?



Answer :

For 8% p-value cutoff , Melissa should use 92% confidence interval

A confidence interval calculated for a treatment effect measure shows the range in which the true treatment effect is likely to fall.

A smaller sample size or higher variability will result in a wider confidence interval with a larger margin of error. The interval width is also influenced by the level of confidence. If you want a higher level of certainty, the interval should be wider.

The width of the confidence interval and the size of the p value are related.

The narrower the interval, the smaller the p value. The confidence interval, on the other hand, provides useful information about the likely magnitude of the effect under consideration as well as the accuracy of the estimate.
