a researcher wants to compare the number of vehicles owned by families in one location to the larger population. Data is collected on the number of vehicles owned by each family. It will be necessary to use this sample data, as well as population data to determine if there is a significant difference between them.
First, identify the test you selected (ztest or t-test)
Second, explain why it was the appropriate test.
Last, Present the results.
Population:
mean number of vehicles: 3.7
Sample:
mean number of vehicles: 4.1
standard deviation: 1
sample size: 100
I worked this problem and got: (I'm unsure of ME and CI)
t=4
Df:100-1=99
alpha: .05
p=.01
ME=0.00784
CI:
4.1 + 0.0078=4.1078
4.1 - 0.00784=4.0922
