Answer:
Hello a value is missing in your question below is the value
samples of n = 10
answer : 24.63 < μ < 25.370
Step-by-step explanation:
Given :
Sample size = n = 10
Z∝/2 = Z0.0256 = 1.95
next calculate for margin of error
E = Z∝/2 * ( 0.6 / /
)
= 0.370
therefore at 94.87% confidence interval the estimated population mean is
x - 0.370 < μ < x + 0.370
25 - 0.370 < μ < 25 + 0.370
24.63 < μ < 25.370
Step-by-step explanation:
let width =x
length=x+14
....
perimeter=96=2*(L+W)
96=2*(X+X+14)
96=4x+28
96-28=4x
68=4x
/4
68/4=x
17=x the width
length = 17+14=31m
....
Check
17+17+31+31=96
I hope it's helpful!
