The heights of a random sample of 100 women are recorded. the sample mean is 65.3 inches and the sample standard deviation is 3 inches. whicho of the following is an approximate 95% confidence interval for the population mean? a. 65.3 + (2)(0.03)b. 65.3 + ()c. 65.3 + (2)(3)d. 65.3 + (2)(30)

B.

Step-by-step explanation:

The confidence interval for the population mean is given by :-

Given : Sample size : n= 100

Sample mean :

Standard deviation:

Level of confidence = 0.95

Significance level :

Critical value :

Then, 95% confidence interval for the population mean will be :-

no, because the sides are not congruent
