Question

A random sample of 100 people was taken. Eighty of the people in the sample favored Candidate A. We are interested in determining whether or not the proportion of the population in favor of Candidate A is significantly more than 75%.
The test statistic is
0.80
0.05
1.15
2.00

Answer 1

Answer:80 percent

Step-by-step explanation:

From the question, the total number of sample is 100 that is hundred(100) people . Eighty (80) people from the sample are in favour of candidate A.

Therefore, the mean statistic is one(1), that is, 0.8+0.05+1.15+2.00= 1.

So, total number from the hundred people supporting Candidate A divided by the total number of sample of the population multiply by a 100 percent;

= 80/100 × 100= 80%.

80% which is greater than 75%
