We have for given data,
Sample mean =15.5
Sample standard deviation =4.5031
Sample size =10
Level of significance= 0.014
Degree of freedom =9
t critical value is (by using t table)= 3.0408
Confidence interval formula is
=(11.17,19.83)
Lower confidence limit= 11.17
Upper confidence limit= 19.83

Use
the confidence level and sample data to find a confidence interval
for estimating the population mean mu. A sociologist develops a
test to measure attitudes towards public transportation, and 35
randomly selected subjects are given the test . If the sample mean
was 81.2 with the sample standard deviation was 24.1, construct a
confidence interval to estimate the population mean if confidence
level is 95%
