Consider a population proportion p = 0.68. a-1. Calculate the expected value and the standard error of P− with n = 30. (Round "expected value" to 2 decimal places and "standard deviation" to 4 decimal places.) a-2. Is it appropriate to use the normal distribution approximation for P− ? Yes No b-1. Calculate the expected value and the standard error of P− with n = 40. (Round "expected value" to 2 decimal places and "standard deviation" to 4 decimal places.) b-2. Is it appropriate to use the normal distribution approximation for P− ?

a) Expected value = 20.4, Standard error = 0.085

b) Yes

c) Expected value = 27.2, Standard error = 0.073

d) Yes

Step-by-step explanation:

We are given the following in the question:

Population proportion, p = 0.68

a) expected value and the standard error

Sample size, n = 30

b) Yes it is appropriate to use normal approximation as:

c) expected value and the standard error

Sample size, n = 40

b) Yes it is appropriate to use normal approximation as:

i wish i could u

step-by-step explanation:

i wish i could u

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
