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.

Manual Dexterity Differences A researcher wishes to see if there is a
difference in the manual dexterity of athletes and that of band members. Two
random samples of 22 are selected from each group and are given a manual
dexterity test. The mean of the athletes' test was 87, and the mean of the band
members' test was 93. The population standard deviation for the test is 7.6. Use
for the mean of the athletes' test. At a=0.05, is there a significant difference in
the mean scores? Use the critical value method and tables.
