Question

Questions 1-17 are related to the following
Below are the values for two variables x and y obtained from a sample of size 5.  We want to build a regression equation based the sample data.

	ŷ = b₀ + b₁x
	y	x
	18	5
	25	10
	9	5
	30	15
	46	18

15	The x and y data are sample data from the population of X and Y to compute b₁ as an estimate of the population slope parameter β₁.  The sample statistic b₁ is the estimator of the population parameter β₁.  The estimated measure of dispersion of the sample statistic b₁ is,
a	0.4121
b	0.4338
c	0.4566
d	0.4840
16	The margin of error for a 95% confidence interval for β₁ is,
a	1.25
b	1.31
c	1.38
d	1.45
17	To perform a hypothesis test with the null hypothesis H₀: β₁ = 0, we need a test statistic.  The test statistic for this hypothesis test is,
a	4.89
b	5.13
c	5.39
d	5.66
