Answer:
Skewed to the left
Step-by-step explanation:
Given
Required
The type of distribution
From the given data, we have:
--- Mean and Median are not equal
and
--- Median is greater than mean
<em>When the median is greater than the mean; the histogram is expected to be left skewed</em>
Answer:
Standard error = 0.34
t-statistic = 11.18
Step-by-step explanation:
Given Data:
Mean difference d = 3.8
Standard deviation S.D = 1.36
Number of people = 16
The appropriate test are:
1. Standard error
2. T- statistic
1. Calculating the standard error using the formula;
Standard error = S.D/√n
= 1.36/√16
= 1.36/4
= 0.34
2. Calculating the t-statistic using the formula;
t-statistic = d/(S.D/√n)
= 3.8/(1.36/√16)
= 3.8/(1.36/4)
= 3.8/0.34
= 11.18
Since there are two halves in a whole, you can times each number by 2 to get the number of halves it has.
12*2=24
10*2=20
13*2=26
15*2=30
8*2=16
5*2=10
The correct answers are: AC CC CA AA
