Answer:
The correct option is C) 21.1 and 0.68
Step-by-step explanation:
Consider the provided information.
The mean composite score was 21.1 with a standard deviation of 4.8. The ACT composite score ranges from 1 to 36, with higher scores indicating greater achievement in high school.
Therefore μ = 21.1 and σ = 4.8
It is given that the sample of 50 students;
Thus, sample size ( n ) = 50
According to the central limit theorem,

Therefore



Hence, the correct option is C) 21.1 and 0.68

Answer:
Length of the garden= 7 feet while the width =28 feet
Step-by-step explanation:
Let the length of the garden be L while the width represented as W
From the question, we deduce the following:
W = 4L
Perimeter = 2(L + W) = 70 feet .... substituting W = 4L into this equation gives
70 = 2(L + 4L)
70 = 2(5L)
70 = 10L ... dividing both sides by 10 gives
L = 7
Recall from the first equation that W = 4L
W = 4 * 7 =28
