Suppose that in a random selection of 100 colored candies, 28% of them are blue. The candy company claims that the percentage of blue candies is equal to 24%. Use a 0.05 significance level to test that claim. Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p=0.24 H:p>0.24 O B. Ho: p=0.24 H4:p<0.24 OC. Ho: p=0.24 H:p#0.24 OD. Ho: p#0.24 H1:p=0.24 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is. (Round two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is. (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Reject Ho. There is sufficient evidence to warrant rejection of the claim that the percentage of blue candies sequal to 24%

A poll of 2,122 randomly selected adults showed that 93% of them own cell phones. The technology display below results from a test of the claim that 92% of adults own cell phones. Use the normal distribution as an approximation to the binomial distribution, and assume a 0.05 significance level to complete parts (a) through (e). Test of p = 0.92 vs p *0.92 Sample X 1 N 2,122 1970 Sample p 0.928369 95% CI The P-value is (Round to three decimal places as needed.) (0.917397,0.939341) a. Is the test two-tailed, left-tailed, or right-tailed? O Two-tailed test O Left-tailed test O Right tailed test b. What is the test statistic? The test statistic is (Round to two decimal places as needed.) c. What is the P-value? Z-Value 1.42 P-Value 0.155

Suppose the null hypothesis is rejected. State the conclusion based on the results of the test. Six years ago, 11.4% of registered births were to teenage mothers. A sociologist believes that the percentage has increased since then. Which of the following is the correct conclusion? O A. There is sufficient evidence to conclude that the percentage of teenage mothers has remained the same. O B. There is sufficient evidence to conclude that the percentage of teenage mothers has increased. O C. There is not sufficient evidence to conclude that the percentage of teenage mothers has remained the same. O D. There is not sufficient evidence to conclude that the percentage of teenage mothers has increased.

A news article that you read stated that 54% of voters prefer the Democratic candidate. You think that the actual percent is larger. 129 of the 212 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v| Select an answer v (please enter a decimal) H1:|? v|| Select an answer v (Please enter a decimal) c. The test statistic ? v (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? v a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly larger 54% at a = 0.10, so there is sufficient evidence to conclude that the proportion of voters who prefer the Democratic candidate is equal to 54%. O The data suggest the…

Suppose that in a random selection of 100 colored candies, 25% of them are blue. The candy company claims that the percentage of blue candies is equal to 22%. Use a 0.05 significance level to test that claim. O A. Ho p=0.22 Hy p>0.22 O B. Ho p=0.22 H p 0 22 O C. Ho pt0.22 H p=022 O D. Ho p=0.22 H1 p<0.22 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed ) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is | (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Fail to reject Ho. There is not sufficient evidence to warrant rejection of the claim that the percentage of blue candies is equal to 22% O B. Reject Hn. There is sufficient evidence to warrant rejection of the claim that the percentage of blue candies is equal to 22% OC. Fail to reject Ho.

whats the test statistic for this hypothsis test AND P value hypothesis test

2. The steps of hypothesis testing You intend to draw a random sample in order to test a hypothesis about an unknown population mean. You will use a hypothesis test. A description of each of the steps of a hypothesis test follows, but they may be specified in the incorrect order. Specify the correct order of the steps.       Determine the null and alternative hypotheses.      Select a level of significance.      Make a decision about the unknown population.      Select a sample and compute the z-score for the sample mean.

A student compared organic food prices at Grocery 1 and Grocery 2. The same items were priced at each store. The first three items are shown in the accompanying Figure A. Choose the correct accompanying output (B or C) for the appropriate test, explaining why you chose that output. Then test the hypothesis that the population means are not equal using a significance level of 0.05. Assume i Figure A and Outputs Click the icon to view Figure A and the outputs. Which is the correct output (B or C) for the appropriate test? Explain. (Figure A) Food Grocery 1 0.89 Grocery 2 0.99 A. Output B is appropriate because the data are paired samples. Bananas/1 Ib Grape tomatoes/1 Ib Russet potato/5 Ib 4.19 4.49 B. Output C is appropriate because there are two samples. 4.69 4.49 C. Output B is appropriate because n2 25. (Figure B) D. Output C is appropriate because the data are independent samples. N Mean StDev SE Mean Test the hypothesis that the population means are not equal using a significance…
