Step-by-step explanation:
-52/4 = -(13 × 4)/4

Answer:
The interval is (2.7512, 2.8488)
Step-by-step explanation:
Given that:
The mean (μ) = 2.9 hours
The standard deviation (σ) = 0.24 hours
n = 14 pound turkey
The confidence interval (c) = 95% = 0.95
α = 1 - 0.95 = 0.05
The Z score of is the z score of 0.025 which is the same z score of 0.475 (0.5 - 0.025).
Therefore the margin of error E is given as
E = = 1.96 × 0.0759 = 0.1488
The interval is = (2.9 - 0.1488, 2.9 + 0.1488) = (2.7512, 2.8488)
The interval is (2.7512, 2.8488)
Dude this question is asking you which of these do you need help with.
