Sample 1: 78,82,85,87,90,85,79,86,91,88

Question

Sample 2: 81,29,80,86,89,92,82,88,84,87
What is the daily high temperature of Sample 1 and Sample 2.
What is the mean daily high temperature of the two samples differ by

Answer 1

- The daily high temperature of Sample 1 is 91 and Sample 2 is 92.
- The mean daily high temperature of Sample 1 is (78+82+85+87+90+85+79+86+91+88) / 10 = 85.1
- The mean daily high temperature of Sample 2 is (81+79+80+86+89+92+82+88+84+87) / 10 = 84.8
- The difference between the mean daily high temperatures of the two samples is 85.1 - 84.8 = 0.3.
