Using the information obtained from a study on heart rate, the following data were obtained for the hypothesis test:• A doctor is testing the claim that the average heart rate of patients is less than 70 bpm.• Assume the significance level is a = 0.05.• The z- test statistic is calculated as -2.01.What is the p-value and conclusion for this hypothesis test?Move the blue dot to choose the appropriate test (left-, right, or two-tailed). Use the graph below to move the slider tohe test statistic in order to find the p-value. Then, make a conclusion based on those results.

It is given that the claim is that the average heart rate of patients is less than 70 bpm.

The recommended dietary allowance (RDA) of vitamin C for women is 75 milligrams (mg) per day. A hypothesis test, with a significance level of 0.05, is to be performed to decide whether adult women are, on average, getting less than the RDA of 75 mg per day. A researcher gathers data from a random sample of women in order to carry out the test. Determine the Null and Alternative hypotheses.
Under what circumstances is the t statistic used instead of the Z score for a hypothesis test?
In a survey taken in 2020, 20 out of 50 women and 17 out of 45 men said that they felt our country was headed in the wrong direction regarding universal health care. Do these data provide sufficient evidence at the 0.01 level of significance to conclude that the proportions of women and men that feel out country is headed in the wrong direction regarding healthcare are equal? Use the P-Value Method of Testing. In your work space below, you will need to have -1. The null hypothesis, Ho 2. The alternative hypothesis, H1 3. The test statistic 4. The type of test(left, right, two-tailed) and the p-value 5. The decision to accept Ho or reject Ho
Find the P-value for the indicated hypothesis test with the given standardized test statistic, zDecide whether to reject H_{0} for the given level of significance Two-tailed test with test statistic z = - 1.5 and alpha = 0.08
Use the pulse rates in beats per minute (bpm) of a random sample of adult females listed in the data set available below to test the claim that the mean is less than 70bpm. Use a 0.05 significance level. Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? A. H0: μ=70 bpm H1: μ>70 bpm B. H0: μ>70 bpm H1: μ<70 bpm C. H0: μ=70 bpm H1: μ<70 bpm D. H0: μ=70 bpm H1: μ≠70 bpm Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. ▼ Reject Fail to reject H0. There is ▼ sufficient not sufficient evidence to conclude that the mean of the population of pulse rates for adult females is ▼ not less than greater than 70 bpm.
Based on this information, give us the t statistic for the sample and the standardized effect size of the hypothesis test. Then tell if we should reject or fail to reject the null hypothesis.
If a researcher obtained a P-value of 0.01 for a hypothesis test that has a significance level of 0.05, what conclusion should the researcher make? 1 The null hypothesis should not be rejected. 2 The alternative hypothesis should not be rejected. 3 The null hypothesis should be rejected. 4 The alternative hypothesis should be rejected. 5 The null hypothesis must be false.
The rate of allergies in children was 15% in 2002. A medical researcher is curious whether advances in medicine have reduced this proportion and decides to conduct a hypothesis test. In a random sample of 500 children, he finds that 65 of them have allergies. Conduct an appropriate hypothesis test in questions #17 - #20. Using the P-Value from the previous question, what is the conclusion of our hypothesis test at the α = 0.05 significance level? Reject the null hypothesis. We have sufficient evidence to conclude that the rate of allergies in children has decreased since 2002. Do not reject the null hypothesis. We do not have sufficient evidence to conclude that the rate of allergies in children has decreased since 2002. The test was inconclusive.
Given that the P-value for the hypothesis test is 0.000 when rounded to three decimal places, what do you conclude? What do the results indicate about the rule that women and children should be the first to be saved?
In a sample of 150 hospital emergency admissions with a certain diagnosis, 128 listed vomiting as a presenting symptom. Do these data provide sufficient evidence to indicate, at the 0.01 level ofsignificance, that the population proportion is less than 0.92? What is the null hypothesis? What is the test statistic? What is the p-value? What is the conclusion?
The Nero Match Company sells matchboxes that are supposed to have an average of 40 matches per box, with ? = 7. A random sample of 92 matchboxes shows the average number of matches per box to be 42.2. Using a 1% level of significance, can you say that the average number of matches per box is more than 40? (a) Find (or estimate) the P-value. (b) Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? (Select below). At the ? = 0.01 level, we reject the null hypothesis and conclude the data are fewer than 40 matches per box. At the ? = 0.01 level, we reject the null hypothesis and conclude that there are more than 40 matches per box. At the ? = 0.01 level, we fail to reject the null hypothesis and conclude that there are fewer than 40 matches per box. At the ? = 0.01 level, we fail to reject the null hypothesis and conclude that there are more than 40 matches per box.
Use the pulse rates in beats per minute (bpm) of a random sample of adult females listed in the data set available below to test the claim that the mean is less than 67bpm. Use a 0.01 significance level. Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? A. H0:μ>67bpm H1:μ<67bpm B. H0:μ=67bpm H1:μ<67bpm C. H0:μ=67bpm H1:μ>67bpm D. H0:μ=67bpm H1:μ≠67bpm Determine the test statistic. ______________ (Round to two decimal places as needed.)
