Problem 1: Descriptive Statistics

Forecast the mean, median, and style of the following datum set: 5, 7, 3, 8, 7, 6, 4, 7, 5.

Result:

Mean: (5+7+3+8+7+6+4+7+5) / 9 = 5.78

A investigator require to essay if the average meridian of students in a school is outstanding than 160 cm. A sample of 30 students has a mean height of 162 cm with a standard divergence of 10 cm. Bear a hypothesis trial at the 5 % significance point.

Solution:

Null Hypothesis (H0): μ ≤ 160 cm
Alternative Hypothesis (H1): μ > 160 cm
Test Statistic: t = (162 - 160) / (10 / √30) = 1.83
Critical Value: Use a t-distribution table with 29 stage of freedom and a 5 % significance level, the critical value is approximately 1.699.
Decision: Since the examination statistic (1.83) is great than the critical value (1.699), we reject the null hypothesis.
