Answer:
- The value of x is 148
- The best point estimate of population proportion is 74%
Step-by-step explanation:
Sample size = n = 200
Number of employees who prefer the new coffee = 148
The formula to calculate the point estimate is:
Here, x is the number of outcomes of our interest i.e. the number of employees who prefer the new coffee brand over the old one. Therefore,
x = 148
Using the values in the above formula, we get the point estimate as:
Therefore, the best point estimate for the population proportion is p = 74%
So, the correct statements for this scenario are:
- The value of x is 148
- The best point estimate of population proportion is 74%
