Answer:
sample size n would be 149305 large
Value of n (149305) is too high, this will be the practical problem with attempting to find this confidence interval
Step-by-step explanation:
Given that;
standard deviation α = 150 min
confidence interval = 99%
since; p( -2.576 < z < 2.576) = 0.99
so z-value for 99% CI is 2.576
E = 1 minutes
Therefore
n = [(z × α) / E ]²
so we substitute
n = [(2.576 × 150) / 1 ]²
n = [ 386.4 ]²
n = 149304.96 ≈ 149305
Therefore sample size would be 149305 large
Value of n is too high, that would be the practical problem with attempting to find this confidence interval
Answer:
Area=15
Perimeter=16
Step-by-step explanation:
First, section the shape off by easier work with shapes.
The two end triangles can then form one large rectangle that is 5in. x 3in.
Next just multiply the length times the width for the area which is 15 in., and add all of the sides up, which will give you 16 in.
