Answer:
The test statistic for this hypothesis test for a proportion is z=1.90.
Step-by-step explanation:
This is a hypothesis test for a proportion.
The claim is that the unemployment rate is less than 5%.
Then, the null and alternative hypothesis are:
The sample has a size n=1500.
The sample proportion is p=0.061.
The standard error of the proportion is:
Then, we can calculate the z-statistic as:
Answer:
The probability that the hail storm will happen on a Saturday is 0.1667.
Step-by-step explanation:
The month of June started on Friday.
Then June 2 is a Saturday.
Remaining 28 days.
Each week has 7 days.
There will be 4 full weeks for the month of June.
So there will be 4 more Saturdays.
Thus, there are a total of 5 Saturdays in the month of June.
Compute the probability that the hail storm will happen on a Saturday as follows:
Thus, the probability that the hail storm will happen on a Saturday is 0.1667.
