Rachel'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. Rachel finds that 350 is in the confidence interval she constructed. What should she do? a) reject the null b) fail to reject the null
