Determine whether the claim represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis? (b) fails to reject the null hypothesis? A researcher claims that less than $16 \%$ of people had no health care visits in the past year.

Now what is this statement? A researcher claims that the standard deviation off the life off a certain type of lawn mower is at most 2.8 years. So the standard deviation is at most two point ideas. So which means this is less than or equal to two point. This is going to be my null hypothesis. See, I have unequal to sign. So this will go into the hypothesis and my alternative hypothesis will be that my sigma or my sanity vision is greater than 2.8 years now. If I had object minor like this is what did I see? I will say that I have enough statistical evidence to say that the standard deviation is more than 2.8 years. Andi. If I failed to reject final hypothesis, I will say that I do not have enough statistical evidence to say that the standard deviation off the life of a certain type of lawn mower is more than 2.8 years. All right, this will be my answer

In this question, just like problems. 70. We're looking at this director of an advertising agency, Andi. She's concerned with the effectiveness of a television commercial. So Paul a RCIs What is the null hypothesis if she makes a correct decision, Type A when she correctly says the commercial is not effective. So with a Type A, it means that the null hypothesis is true on That's what we concluded. So if she concludes the correct null hypothesis, it must mean that she is testing. The commercial is not effective. Part B is very similar this time. She's making a Type B correct decision when she correctly says that the commercial is not effective. So with a type B, it means that the no hopeful says is false on that is what we concluded. So if by saying that it's not effective, she is concluding a false hypothesis, it must mean there are no hypothesis is the opposite of what she is concluding. So commercial is effective is what should be testing

A government agency claims that more than 75% of full time workers on over $538 for me more than 75 which means my proportion is greater than 0.75 This is going to be my alternative hypothesis. This is my alternative hypothesis. What will be my null hypothesis? My null in this case would be that he is less than or equal to 0.75 Okay, No. How are we going toe? Interpret the decision. If we reject the null hypothesis Well, internal hypothesis is rejected. We will say that we have enough evidence to say that yes, 75% or more people who are fully who are full time employed do earn 538 is perfect. But if we fail to reject the null hypothesis, we will say that we do not have sufficient evidence to say that more than 75% off full time workers on over $538 per week. And this would be my answer

A sports drink maker, claims that the mean calorie content off its beverages is 72 calories for serving. So this is going to be my null hypothesis and working. My, alternatively, that the mean calorie content person is not 70 now. If I were to reject final hypothesis, I would say that I have enough statistical evidence to such as that the main calorie content is something other than 72 for serving right 72 calories per serving something other than that. And if I were, if I would fail to reject Mandel hypothesis, I would say that I do not have enough statistical evidence to say that my mean calories for serving is something other than 72 this would be my answer.
