(c) Based on the shape of the histogram and boxplot, explain why a large sample size is necessary to perform inference on the mean using the normal model. The population distribution is likely to not be normal because the histogram is skewed right and the boxplot shows outliers. (d) Does the evidence suggest that the volume of this company's stock has changed in recent years? Use an a = 0.05 level of significance. Determine the hypotheses. = 7.52 Họ: H H: H * 7.52 (Type integers or decimals. Do not round.) Find the test statistic. (Round to two decimal places as needed.)
