Please solve the standard deviation!
Extracted text: You work for a consumer watchdog publication and are testing the advertising claims of a tire manufacturer. The manufa test 16 tires and get the following life spans. Complete parts (a) through (c) below. 48,854 41,439 26,895 38,919 32,129 39,649 41,423 35,083 D 24,680 32,992 39,044 36,579 34,198 38,590 36,914 45,120 4. 2. 2- 27,097 46,437 27,097 46,437 Distance (in miles) Distance (in miles) Is it reasonable to assume that the life spans are normally distributed? Why? Choose the correct answer below. A. Yes, because the histogram is symmetric and bell-shaped. B. No, because the histogram is neither symmetric nor bell-shaped. OC. No, because the histogram is symmetric and bell-shaped. D. Yes, because the histogram is neither symmetric nor bell-shaped. (b) Find the mean of your sample. The mean is 37031.8. (Round to one decimal place as needed.) Find the standard deviation of your sample. The standard deviation is | (Round to one decimal place as needed.)
