Suppose that a travel bureau claims that the trees in a forest are 83 feet tall on average, With a standard deviation of 2 feet

valentinak56 [21]

Answer:

Step-by-step explanation:

Given mean = 84,

Standard deviation = 2,

Sample 64,

95% confidence interval: z = 1.96

Applying empirical rule , means that 95% of data fall within two standard deviations.

ME = = 0.49

Rounding this to 0.5

CI = 83.5< mean < 84.5

Outside of this range= x ≤ 83.5 and ≥ 84.5
