Find the margin of error for 96% confidence interval with standard error 6 -0.4 for simple random sample size of 100. Formula: 1. The margin of error (m) (Critical Value) (Standard Error) 2. Find critical value using step to question No 15. 3. Find population Standard error using relation: n Check Your Understanding] An IQ test was given to a simple random sample of 75 students at a certain college. The sample mean score was 105.2. Scores on this test are known to have a standard deviation of = 10. Construct a 90% confidence interval for the mean IQ score of students at this college. Formula: 1. Confident Interval of population mean : (x-m)>u
