The average length of time it takes to read a book can differ from one generation to another. However, the standard deviation of this reading time seems to stay steady at around 2.2 hours. A study of 50 readers from the current generation was conducted to check if the average reading time is at most 17 hours. The sample mean was 16.1 hours, with a sample standard deviation of 1.4 hours. Does the data support the claim at the 5% significance level?
