Finding P-Values and Critical Values. In Exercises 17-24, assume that the signifi- cance level is a = 0.05; use the given statement and find the P-value and critical values. (See Figure 8-4.) 18. The test statistic of z =-2.00 is obtained when testing the claim that p < 0.5. 20. The test statistic of z 1.50 is obtained when testing the claim that p 0.25. 24. With H: p > 7/8, the test statistic is z = 2.88.

It describes the respiratory rate in males and females. A person's respiratory rate is the number of breaths you take per minute. The normal respiration rate for an adult at rest is 12 to 20 breaths per minute. Compare females and males with independent sample t-test and make a conclusion whether these two groups are different. IMPORTANT: In your response, write null hypothesis and alternative hypothesis; your chosen a-level; p-level for calculated t-test; your decision on whether you reject null hypothesis.

CONFLICT RESOLUTION 2 of 4 What is the critical z/t score at α = 0.05? The Center for the Study of Violence wants to determine whether conflict-resolution program in a particular high school reduces aggressive behavior among its students. For 8 students, aggression was measured both before and after they participated in the conflict resolution course. What is the critical z/t score at α = 0.05? Their scores are below:
A test of the claim that the proportion of residents with that least two jobs is more than 53% produces the test statistic z = 1.68 Find the P-value.
True or False a. The t-table is to be used to get the critical or tabulated value when conducting a z-test . b. The degrees of freedom is necessary when determining the tabulated value or the critical value (TV) in a z-test. c. In order to know whether a hypothesis test is one-tailed or two-tailed, the null hypothesis should be taken into consideration.
Critical Values. In Exercises 21–24, refer to the information in the given exercise and do the following. a. Find the critical value(s). b. Using a significance level of α = 0.05, should we reject H0 or should we fail to reject H0? Exercise 18
Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. H0: p=0.2 versus H1: p>0.2 n=125; x=30; α=0.05 What is the test statistic z0 and what is the P-value?
Water Consumption The Old Farmer’s Almanac stated that the average consumption of water per person per day was 123 gallons. To test the hypothesis that this figure may no longer be true, a researcher randomly selected 16 people and found that they used on average 119 gallons per day and s = 5.3. At α = 0.05, is there enough evidence to say that the Old Farmer’s Almanac figure might no longer be correct? Use the Critical Value method.
Test the claim that the mean GPA of night students is significantly different than the mean GPA of day students at the 0.02 significance level. The sample consisted of 30 night students, with a sample mean GPA of 2.67 and a standard deviation of 0.02, and 65 day students, with a sample mean GPA of 2.62 and a standard deviation of 0.05.The test statistic is: ________________ (to 2 decimals)The positive critical value is: _________________ (to 2 decimals)Based on this we: Reject the null hypothesis Fail to reject the null hypothesis
Test the claim that the mean GPA of night students is significantly different than the mean GPA of day students at the 0.05 significance level. The sample consisted of 30 night students, with a sample mean GPA of 3.07 and a standard deviation of 0.05, and 20 day students, with a sample mean GPA of 3.06 and a standard deviation of 0.03. The test statistic is: (to 2 decimals)The positive critical value is: (to 2 decimals)
how do i put part c into the computer? Takeout Food A magazine article reported that 15% of adults buy takeout food every day. A fast-food restaurant owner surveyed 220 customers and found that 42 said that they purchased takeout food every day. At =α0.05, is there evidence to believe the article's claim? Use the critical value method with tables. Do not round intermediate steps. (a)State the hypotheses and identify the claim. (b)Find the critical value(s). (c)Compute the test value. (d)Make the decision. (e)Summarize the results.
