Anews organization previously stated that three of four people believed that the state of the economy was the country's most significant concern. they would like to test the new data against this prior belief. the most appropriate hypotheses are: a. h0: p = 0.75, ha: p > 0.75. b. h0: p = 0.65, ha: p < 0.65. c. h0: p = 0.65, ha: p > 0.65. d. h0: p = 0.75, ha: p ≠ 0.75.

Option d)

Step-by-step explanation:

We are given the following in the question:

Three of four people believed that the state of the economy was the country's most significant concern.

They would like to test the new data against this prior belief.

The null hypothesis will state that the three of four people believed that the state of the economy was the country's most significant concern.

The alternate hypothesis will state that this is not true. It states that people believed that the state of the economy was the country's most significant concern is not the same.

We design the null and the alternate hypothesis  

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

can you rephrase the question ? it is unclear : -)
