The raw data are given as follows: (a) (b) E-mail title A question about normal distribution (c) Re: A question about normal distribution Sorry teacher I did not attend the exam Exam questions Date 10/7/2022 10/7/2022 14/7/2022 14/7/2022 From Table 1, she then counted the number of students who sent 1, 2, 3, .... e-mails. The results are given in Table 2. Table 1: Raw data of all e-mails received from Mathematics students Number of emails sent 1 2 3 4 5 6 7 Frequency 80 41 16 7 Student Anne Hamid Freddy Hansen 5212. How many emails did the teacher receive? Henry Liew Thomas Hasler 8 21 Total Table 2: Frequency table of number of students who sent 1,2,3,... emails. 1 155 Find the percentage of students who sent 3 or less emails to the teacher. Find the mean and standard deviation of the number of e-mails sent. Compare the mean with the median. Which one is larger? What does this tell you about the skewness for the distribution of number of e-mails sent?
