Question

​(e) what might you conclude if a random sample of 3636 time intervals between eruptions has a mean longer than 104104 ​minutes? select all that apply.
a. the population mean may be greater than 9191.
b. the population mean may be less than 9191.
c. the population mean must be less than 9191​, since the probability is so low.
d. the population mean must be more than 9191​, since the probability is so low.
e. the population mean is 9191​, and this is an example of a typical sampling result. f. the population mean cannot be 9191​, since the probability is so low. g. the population mean is 9191​, and this is just a rare sampling.

Answer 1

The answer in this question is A, D and E, we might conclude if a random sample of 36 time interval between eruption has a mean longer that 104 minutes, I can conclude that the population means may be greater than 91 and the probability mean must be more that 91, since the probability is low and also the population mean is 91, and this is an example of a typical sampling result.
