Answer:
The critical values are -1.96 and 1.96.
Step-by-step explanation:
The test is a two-tailed test because the alternate hypothesis (Ha) is expressed using not equal to.
To find the critical values for a two-tailed test, divide the significance level by 2 (0.05/2 = 0.025)
The critical values at z0.025 are -1.96 and 1.96
Answer:
x = 7.6
Step-by-step explanation:
We know the opposite side and the adj side and this is a right triangle
tan theta = opp / adj
tan 66 = 17/x
x tan 66 = 17
x = 17 /tan 66
x=7.56888
To the nearest tenth
x = 7.6
