The volume of a stock is the number of shares traded for a given day. Several years ago, a certain company's stock had a mean daily volume of 7.52 million shares, according to a reputable financial news outlet. A random sample
of 40 trading days in a recent year was obtained and the volume of shares traded on those days was recorded, with the accompanying results. Complete parts (a) through (d) below.
E Click the icon to view the shares data.
(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 oa = 0.05 level of significance.
Determine the hypotheses.
Họ: H
= 7.52
H1: H
(Type integers or decimals. Do not round.)
7.52
Find the test statistic.
to =L
(Round to two decimal places as needed.)
