Answer:
Confidence interval for the true mean number of reproductions per hour for the bacteria is (10.1,10.5).
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 10.3
Population standard deviation, σ = 2.1
Sample size, n = 728
Alpha, α = 0.01
Confidence interval:

Putting the values, we get,


combine like terms
exponent
12y^2 = 12
144y = 12
