2. suppose that 62 random samples based on ten student responses to the question, "how many text messages do you send per day? " resulted in the 62 sample means
(rounded) shown below.
65 68 76 76 78 82 83 83 85 86 87 88 88
88 89 89 89 90 91 91 91 91 92 92 92 92
92 93 93 93 93 93 94 94 94 94 94 94 95
95 95 95 95 95 95 95 96 96 97 97 97 98
98 98 98 98 99 100 100 101 104 106
a. draw a dot plot for the distribution of sample means.
b. based on your dot plot, would you be surprised if the actual mean number of text messages sent per day for all eleventh graders in the school is 91.7? why or why not?
