Answer:
The value of the test statistic is
Step-by-step explanation:
Central Limit Theorem
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
Our test statistic is:
In which X is the sample mean, is the expected mean, is the standard deviation and n is the size of the sample.
A publisher reports that 52% of their readers own a laptop.
This means that
Sample of 180:
Means that
By the Central Limit Theorem:
A random sample of 180 found that 46% of the readers owned a laptop.
This means that
Find the value of the test statistic.
The value of the test statistic is
