You have a one-sided hypothesis test with alpha level 0.05 and p-value of 0.04.Which of the statements below is false?The rejection area at the tail is 0.05.In this example, the p-value would be describing the likelihood of thissample (or a more extreme one) occurring if the null hypothesis was true,in two directions.The outcome of the test would change if the test was two-sided instead ofone-sided because that would mean each tail would be assigned half ofalpha only.A higher value of alpha would not have changed the outcome of the test.A higher value of p-value would have changed the outcome of the test.

Answered: You have a one-sided hypothesis test…

A car leasing firm's records indicate that the mean number of miles driven annually in its cars has been about 13,000 miles. The firm suspects that this number has decreased this past year. Suppose that the firm wishes to choose a small sample of driving distances from the past year and carry out a hypothesis test for its suspicion. State the null hypothesis Ho and the alternative hypothesis H, that it would use for this test. Ho: 0 H;: 0 S Oロロ2ロロ=ロロチロ

You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly different from 0.85. You use a significance level of α=0.002. H0:p=0.85H0:p=0.85 H1:p≠0.85H1:p≠0.85You obtain a sample of size n=415n=415 in which there are 361 successes.What is the p-value for this sample? (Report answer accurate to four decimal places.)p-value =
We want to compare cholesterol levels between men and women, so we collect a sample of 20 women and 30 men. The group of men in our sample have a mean of 240.0 with standard deviation 35.0, and the women have a mean of 210.0 with standard deviation 30.0. What is the null hypothesis? Note that two-sample problems (like this one) were not discussed in class, but you should know the answer (or at least be able to provide a good guess below) based on what was covered in class. Group of answer choices The mean cholesterol level in men is equal to the mean cholesterol level in women The mean cholesterol level in men is different than the mean cholesterol level in women The mean cholesterol level in men is less than the mean cholesterol level in women The mean cholesterol level in men is less than the mean cholesterol level in women
A researcher investigates the effectiveness of a new treatment for OCD (i.e., obsessive-compulsive disorder) in a clinical population that is known to have a mean OCD score of μ = 28. The results will be examined by a z-test, p < 0.05 2-tails test. Which of the following is the correct statement of the null hypothesis for the test?A. μ ≠28 (i.e., the treatment has no significant effect).B. μ ≠28 (i.e., the treatment has a significant effect).C. μ = 28 (i.e., the treatment has a significant effect).D. μ = 28 (i.e., the treatment has no significant effect).
Which of following is not true about the null hypothesis? Suggesting that there is an absence of effect Our sample would have the same mean as our population because there is a chance our sample would have a different mean than our population. The population mean of students at CSU will equal the population mean of students at universities in the U.S. There are two-tailed and one-tailed null hypotheses.
A test of H0: p = 0.4 versus Ha: p > 0.4 has the test statistic z = 2.52. Part A: What conclusion can you draw at the 5% significance level? At the 1% significance level? Part B: If the alternative hypothesis is Ha: p ≠ 0.4, what conclusion can you draw at the 5% significance level? At the 1% significance level?
Choosing the alpha level for a hypothesis test allows researchers to control the probability of committing a type II error. True or False? I see two different answers given for this question.
A researcher studies the effect of cognitive psychotherapy on positive self-regard. The number of positive statements made about oneself is recorded for each participant during the first meeting. After 8 weekly therapy sessions, the measures are repeated for each person. The therapist predicts that cognitive psychotherapy will increase the number of positive statements. For the following data: Before Treatment: 7, 6, 9, 5 After Treatment: 10,12,7,17 What is the null hypothesis for the study?
In 2001, the average proportion of the people with a cell phone was 34%. Has that proportion changed? what is the null and alternative hypothesis for this scenario. Then write for a type I and type II error in context of this scenario.
ssume that your sample(s) comes from a normally distributed population. Please show all work. State the null hypothesis and alternative hypothesis. State your decision in terms of the null hypothesis and the alpha level. State your results in standard APA format. What, if any relationship, exists between self-reported height for females and self-reported weight for the same female participants? Write a null and an alternative hypothesis for this research question (you may want to review Example 15.7 and Example 15.8 on page 508). Determine the relationship between the two measures for this sample (calculate r). Discuss and interpret the relation strength and direction indicated by this statistic. Test your hypothesis. Report your decision. Then, report your results using standard APA format (see page 509 in your text). Please only solve the last 3 bullets
If you use a 0.05 level of significance in a two-tail hypothesis test, what decision will you make if ZSTAT = +1.2
A claim is made that 25% of American college students go to a beach for spring break. You believe this claim is incorrect. You would like to test the null hypothesis that p = 0.25 versus the alternative hypothesis that p ≠ 0.25. You gather data from a random sample of 100 college students and obtain a test statistic of 3.3. If we assume the significance (or alpha) level is 0.01, what should your decision be? 1. Reject the null hypothesis 2. Fail to reject the null hypothesis 3. Reject the alternative hypothesis 4. Fail to reject the alternative hypothesis 5. We cannot reach a conclusion without knowing the sample proportion.
