////// The answer is: 4x+2
The 99% confidence interval for the true mean is given by:

where:

is the sample mean = 69.7

is the standard deviation = 2.8

is the test statistics = 2.58 for for 99% confidentce interval.
n is the sample size = 772.
Therefore, the 99% confidence interval is:
Answer:
87
Step-by-step explanation:
Population standard deviation = σ = 37 grams
Confidence interval = 94%
(1-α)×100% = 94
⇒α = 0.06
From table z table and interpolation
z = 1.881
L = Confidence interval length = 15
N = Number of samples

∴ Number of turtles must she must weigh is 87
