State whether the standardized test statistic t indicates that you should reject the null hypothesis. Explain. (a) t (b) t (c) t (d) t -4 0 4 t A normal curve is over a horizontal axis and is centered at 0. Vertical line segments extend from the horizontal axis to the curve at negative t@Sub{0}=negative 2.058, 0 and t@Sub{0}=2.058, where negative t@Sub{0}=negative 2.058 is to the left of 0 and t@Sub{0}=2.058 is to the right of 0. The area under the curve to the left of negative t@Sub{0}=negative 2.058 and to the right of t@Sub{0}=2.058 is shaded. (a) For t, should you reject or fail to reject the null hypothesis?

For the following questions, state whether you would reject or
fail to reject the null hypothesis:
Critical value z > 1.96 or z < -1.96
Test value: -2.87
Critical value z > 2.33
Test value: 1.85
Critical value z > 2.33
Test value: -2.87
Two tailed z test with an α=0.05
Test value: 1.85
One tailed z test in the positive direction with an α=0.01
Test value: 8.56

A t statistic was used to conduct a test of the null hypothesis
H0: µ = 11 against the alternative Ha: µ ≠
11, with a p-value equal to 0.042. A two-sided confidence interval
for µ is to be considered. Of the following, which is the largest
level of confidence for which the confidence interval will NOT
contain 11?
A 90% confidence level
A 92% confidence level
A 96% confidence level
A 97% confidence level
A 98% confidence level
