Need help w/ questions 31 & 32. Thank you.

To figure out whether our sample appears to have come from a population exhibiting a normal distribution, which of the following is least useful? O Measuring the mean and variance to see if they are equal. Performing a Shapiro-Wilk test on the data. O Judging the linearity of values on a quantile plot of the data. Creating a histogram of the data and looking at it carefully. Question 32 1 pts The t-test is fairly robust to deviations from normality for large sample sizes, even though this is an assumption of the method. This is because the central limit theorem states that the distribution of sample data will be normal. the distribution of sample means will be normal. the distribution of population means will be normal. the distribution of population data will be normal
