solve this question

Suppose a geyser has a mean time between eruptions of 96 minutes. Le 22 minutes. Complete parts (a) through (e) below. (a) What is the probability that a randomly selected time interval between eruptions is longer than 106 minutes? The probability that a randomly selected time interval is longer than 106 minutes is approximately|]. (Round to four decimal places as needed.) (b) What is the probability that a random sample of 12 time intervals between eruptions has a mean longer than 106 minutes? The probability that the mean of a random sample of 12 time intervals is more than 106 minutes is approximately (Round to four decimal places as needed.) (c) What is the probability that a random sample of 25 time intervals between eruptions has a mean longer than 106 minutes? The probability that the mean of a random sample of 25 time intervals is more than 106 minutes is approximately (Round to four decimal places as needed.) (d) What effect does increasing the sample size have on the probability? Provide an explanation for this result. Fill in the blanks below. If the population mean is less than 106 minutes, then the probability that the sample mean of the time between eruptions is greater than 106 minutes because the variability in the sample mean as the sample size (e) What might you conclude if a random sample of 25 time intervals between eruptions has a mean longer than 106 minutes? Select all that apply. OA. The population mean must be less than 96, since the probability is so low. [)B. The population mean cannot be 96, since the probability is so low. [) C. The population mean is 96, and this is an example of a typical sampling result. OD. The population mean may be less than 96. OE. The population mean is 96, and this is just a rare sampling. OF. The population mean must be more than 96, since the probability is so low. [) G. The population mean may be greater than 96
