Answer:
Width
Step-by-step explanation:
When we have quantitative data it is grouped in classes. There are three ways in which the data can be grouped they are:
Single value grouping where each class has one distinct value.
In Cutpoint grouping is used when the observations have decimal points
In Limit grouping a classes are set based on a specified range of values. Here limit grouping is being done and the range of each class is called width.
Answer: 0.0010
Step-by-step explanation:
Given the following :
Population Mean(m) = 4.2 years
Sample mean (s) = 3.9
Standard deviation (sd) = 0.6
Number of samples (n) = 38
Calculate the test statistic (z) :
(sample mean - population mean) / (sd / √n)
Z = (3.9 - 4.2) / (0.6 / √38)
Z = (- 0.3) / (0.6 / 6.1644140)
Z = -0.3 / 0.0973328
Z = - 3.0822086
Z = - 3.08
From the z table :
P(Z ≤ - 3.08) = 0.0010
<u>Solution:</u>
Substitute the value of the variable into the expression, then simplify.
Answer: -8
