Let p denote the population proportion of the University of lowa students who support the creation of a wealth tax in the U.S.. We want to test Ho: p = 0.5 versus HA: p > 0.5.
Suppose we surveyed a random sample of 200 University of lowa students and got a test statistic value of 1.15. Which of the following R commands give us the correct p
value? Please select all that apply. Hint: this question has two correct answers.

MARC PODUIELION Distribution of incoe is known to be right-skewed. Suppose we take a random sample of the U.S. residents and record their incomes. Which of the following
the sample mean (the average income based on the sample) are true? Please select all that apply.
With a sufficiently large sample size, the sampling distribution of the sample mean resembles the shape of the population distribution.
The sampling distribution of the sample mean is less spread out when the sample size is larger.
With a sufficiently large sample size, the sampling distribution of the sample mean is approximately normal.
The sampling distribution of the sample mean is more spread out when the sample size is larger.
