Suppose you wish to determine if the mean IQ of students on a certain campus is different from the mean IQ in the general population, 100. To conduct this study, you obtain a simple random sample of 90 students on this campus, administer an IQ test, and record the results. The mean IQ of the sample of 90 students is found to be 106.5 with a standard deviation of 13.1. Complete parts (a) through (c) below, Click the icon to view the t-distribution table.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
