Answer: a. 0.1031; fail to reject the null hypothesis
Step-by-step explanation:
Given: Significance level :
The test statistic in a two-tailed test is z = -1.63.
The P-value for two-tailed test : [By p-value table]
Since, 0.1031 > 0.05
i.e. p-value >
So, we fail to reject the null hypothesis. [When p< then we reject null hypothesis ]
So, the correct option is a. 0.1031; fail to reject the null hypothesis.
Answer:
x = = 10.8
Step-by-step explanation:
Both problems are done the same way. I will do the first one and you do the second one. OK?
Move the radius x to make a right triangle. The 6 unit segment bisects the chord. So, the legs of the right triangle are 6 and 9
The use the Pythagorean theorem to find x, which is the hypotenuse of the right triangle. Now,
= 10.8
None of the answer choices are to the nearest tenth. So, I am confused about that.
In the second problem, the answer should be 11.2
