Answer:
(170.251 ; 205.949)
Step-by-step explanation:
Sample size, n = 34
Sample mean, xbar = 188.1
Population standard deviation, σ = 53.1
Confidence level = 95% ; Zcritical at 95% = 1.96
Using the confidence interval relation :
Xbar ± standard Error
Standard Error = Zcritical * σ/√n
Standard Error = 1.96 * 53.1/√34
Standard Error = 17.849
Lower boundary = (188.1 - 17.849) = 170.251
Upper boundary = (188.1 + 17.849) = 205.949
(170.251 ; 205.949)
