Answer:
The given statement is false.
Step-by-step explanation:
We are given the following in the question:
95% confidence interval: (4.53,5.18)
Sample mean, = 4.85 seconds
Sample size, n = 20
Alpha, α = 0.05
Sample standard deviation, σ = 1.47 seconds
Degree of freedom = n - 1 = 19
95% Confidence interval:
Putting the values, we get,
Thus, the calculated confidence interval is different from the given confidence interval.
Hence, the given statement is false.
