describe the steps in the process of statistical hypothesis testing. When stating the conclusion, why do we never accept the null hypothesis
3. A claim is made that the proportion of college students who have Netflix accounts is 0.85. Noah believes this claimed value is too high. He is able to survey a random sample of 240 college students, and he finds that the sample proportion who have Netflix accounts is 0.82. Noah proceeds to use this data to conduct a hypothesis test. Based on this information, which one of the following statements is correct? A. The p-value will be smaller than 0.01 but larger than 0. B. The p-value will be between 0.01 and 0.05. C. The p-value will be between 0.05 and 0.10. D. The p-value will be larger than 0.10.
Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. Write out the hypotheses to be put to the test and define the parameter of interest in context of the problem. Do a minority of Michigan residents clear snow from sidewalks before 9 am after snow has fallen?For this scenario, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem. H0:Ha: The parameter p represents ___(provide appropriate definition in context)________
Is this what significance means? Statistical significance is very often mentioned in research reports. When asked what it means, a student replies that "results that are statistically significant tell us that they cannot easily be explained by chance variation alone if the hypothesis testing was true. Do you think this statement is essentially correct? Explain your answer.

Question 6 In this exercise, we are conducting many hypothesis tests to test a claim. Assume that the null hypothesis is true. If 100 tests are conducted using a significance level of 5%, approximately how many of the tests will incorrectly find significance?Enter your answer in accordance to the question statement of the tests will find significance.
Traditionally in hypothesis testing, the null hypothesis represents the "status quo" which will be overturned only if there is evidence against it. Which of the statements below might represent a null hypothesis? 1. the treatment increase survival rates 2.the teaching method raises SAT score 3. the teaching method does not chang SAT score
Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test. Suppose that 40% of all supermarkets in the US use recyclable plastic bags. We would like to assess if the proportion of supermarkets in Michigan that use recyclable plastic bags is more than the stated rate. For this scenario, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem. H0:Ha: The parameter p represents ___(provide appropriate definition in context)________

Hello can you answer 4 for me
In hypothesis testing, O if the test statistic is negative, this means the sample statistic is larger than the claimed population parameter. we call the initial claim being tested about the population an alternative hypothesis. it is not necessary to know the population size in order to compute the test statistic. the "P" in P-value stands for "personal." results that are statistically significant will always be practically important (or practically significant).
