Please solve the questions below to your best and I will also make sure we are both satisfied if I am satisfied. I really need help. The textbook is provided below but solve it with what's easier for you ( excel, desmos, etc) and everything is not in the textbook!

Questions:

Consider the 4 normal quantile-quantile plots given in the image. One of these illustrates a distribution that is skewed to the right. Which one?

In one part of the study (involving weight at metamorphosis), a sample of 45 female stoneflies yielded a sample mean weight of 158.7 mg, with an associated 95% confidence interval of 147.6 to 169.8 mg. Suppose the assumptions of the procedure they used were met. Of the following options, which one is the best interpretation of that interval? 95% of this population of female stoneflies have a weight at metamorphosis between 147.6 and 169.8 mg. (9 We can be 95% confident that the true mean weight of female stoneflies in this population lies between 147.6 and 169.8 mg. We can be 95% confident that the sample mean weight of the 45 female stoneflies lies between 147.6 and 169.8 mg 0 In repeated sampling, 95% of the 95% confidence intervals calculated in this manner will capture the mean weight at metamorphosis of the female stoneflies in the sample
