To become an actuary, it is necessary to pass a series of 10 exams, including the most important one, an exam in probability and statistics. An insurance company wants to estimate the mean score on this exam for actuarial students who have enrolled in a special study program. They take a sample of 8 actuarial students in this program and find the mean of the sample is 6.0 with standard deviation of the sample 2.0. This sample will be used to calculate a 95% confidence interval for the mean score for actuarial students in the special study program. The critical value used in constructing a 95% confidence interval is ________. Question 16 options: 1) 1.8595 2) 3.4995 3) 2.3646 4) 1.8946

The US Geological Survey complied historical data about Old Faithful Geyser from 1870 to 1987. Let x1 be a random variable that represents the time interval (in minutes) between Old Faithful eruptions for the years 1949 to 1952. Based on 8840 observations, the sample mean interval was x1=65.0 minutes. Let x2 be a random variable that represents the time interval in minutes between Old Faithful eruptions for the years 1983 to 1987. Based in 24404 observations the sample mean time interval was x2=71.2 minutes. Historical data suggest that o1= 8.14 minutes and o2= 11.78 minutes.
