Answer:
Hypothesis test conclusion , average salary ≠ 15
Step-by-step explanation:
Null Hypothesis [H0] : Average Salary = 15
Alternate Hypothesis [H1] : Average Salary ≠ 15
t = (x bar - μ) ÷ (s / √[n])
Sample Mean [x bar] = 16 , Population Mean [μ] = 15 , Standard Deviation [s] = 2.80 , [Sample number] n = 30
t = (16 - 15) / (2.80 / 5.47)
t = 1 / 0.5
t = 2
As calculated value ie 2 > tabulated critical value ie 1.96 , at significance level 0.05. So, we reject the Null Hypothesis.
Hence, as per Alternate Hypothesis, average salary ≠ 15
