Consider the following competing hypotheses:

H₀:_xy= 0

H_A:_xy 0

The sample consists of 27 observations and the sample correlation coefficient is 0.75. UseTable 2.

a.	Calculate the value of the test statistic.(Round your intermediate calculations to 4 decimal places and final answer to 2 decimal places.)

Test statistic

b-1.	At the 5% significance level, specify the critical value(s).(Round your answer to 3 decimal places.)

Critical value

Consider the following sample data:

y	44	52	31	55	24	66	46	39
x1	47	46	22	50	22	56	48	42
x2	22	14	10	17	28	15	14	16

a-1.	Estimate a multiple linear regression model.(Negative values should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to 2 decimal places.)

y-hat = + x₁₊ x₂
