To find: that the criteria for interfering with two samples t are fulfilled yes or not.
Answer to Problem 13PT4
Yes, We have two independent random samples and large
Explanation of Solution
It is compared the survey means of both of these two sums. The T test suggests that the samples are not
Although it is true, the results are generally not distributed since the scale is integers from 0 to 20; the T tests are sufficiently large for the conclusion to be very reliable.
The 10% condition is that nearly the whole population does not take samples. In this scenario, a limited group of over 1100 individuals will have to make a final population correction nowhere within the scale of the country.
Hence, the correct option is (e)
