Question 1163236
z=(p hat-p)/sqrt((0.36*0.64)/290)
=-0.06/0.0282=-2.13
p-value is 0.0166

Answer to 2 is C
Answer to 3 is B
Answer to 4 is C. This is a population proportion, not a mean, and at the 0.01 level, we fail to reject the null hypothesis, so there is insufficient evidence to conclude that the population proportion is < 0.36.
The p-value has to be less than the significance level, since the p-value says what the probability would be of finding a result this extreme or more, and that probability has to be lower than the postulated significance.
