For both questions, provide a screenshot of the online calculator to support your solutions. The mean age of grade 11 students who answered the SEP survey on or before October 31, 2020 is 203.69 months with a standard deviation equal to 15.98 months. If a random sample of 30 students is selected, what is the probability that the mean age for the sample is less than 195 months? b. Assume that the ages given in (a) are normally distributed. Are you more likely to randomly select 1 student with age less than 195 months (16 yrs old) or are you more likely to select a sample of 15 students with a mean age less than 195 months? Explain.
