A bottle contains a label stating that it contains pills with 500 mg of vitamin C, and another bottle contains a label stating that it contains pills with 325 mg of aspirin. When testing claims about the mean contents of the pills, which would have more serious implications: rejection of the vitamin C claim or rejection of the aspirin claim? Considering only a type I error and using the same sample size, is it wise to use the same significance level for hypothesis tests about the mean amount of vitamin C and the mean amount of aspirin? Rejection of the claim about is more serious because the wrong dosage could cause more serious adverse reactions than a wrong dosage. It would be wise to use a significance level for testing the claim about the aspirin.\fThe test statistic of 2 = 2.59 is obtained when testing the claim that p 35 [1.229. a. Identify the hypothesis test as being two-tailed, lefttailed, or righttailed. b. Find the Pvalue. c. Using a signicance level of o = Eli i], should we reject \"D or should we fail to reject H\"? Click here to 1.riew age 1 of the standard normal distribution table. Click here to 1.riew age 2 of the standard normal distribution table. a. This is a |:l test Assume a signicance level of c: = 0.05 and use the given information to complete parts [a] and (b) below. Original claim: More than 53% of adults would erase all of their personal information online it they could. The hypothesis test results in a Pvalue of 11.0384. a. State a conclusion about the null hypothesis. {Reject H0 or fail to reject HO.) Choose the correct answer below. 0 A. Reject Ho because the Pvalue is greater than 0:. O B. Reject Ho because the Pvalue is less than or equal to a. O C. Fail to reject Ho because the P-value is greater than o. O D. Fail to reject HD because the Pvalue is less than or equal to o. Assume a signicance level ofot= 0.111 and use the given information to complete parts [a] and (b) below. Original claim: The mean pulse rate (in beats per minute) of a certain group of adult males is 69 bpm. The hypothesis test results in a P-value of 0.0094. a. State a conclusion about the null hypothesis. {Reject H0 or fail to reject Ho-i Choose the correct answer below. C) A. Reject H.) because the Pvalue is less than or equal to o. C) B. Reject H.) because the Pvalue is greater than a. C) C. Fail to reject Ho because the Pvalue is less than or equal to o. O D. Fail to reject Ho because the Pvalue is greater Than o. The Ericsson method is one of several methods claimed to increase the likelihood of a baby girl. In a clinical trial, results could be analyzed with a formal hypothesis test with the alternative hypothesis of p > 0.5, which corresponds to the claim that the method increases the likelihood of having a girl, so that the proportion of girls is greater than 0.5. If you have an interest in establishing the success of the method, which of the following P-values would you prefer: 0.999, 0.5, 0.95, 0.05, 0.01, 0.001? Why? The P-value of is preferred because it corresponds to the sample evidence that most strongly supports the hypothesis that the method effective.Claim: A minority of adults would erase all of their personal information online 'rf they could. A software rm survey of 470 randomly selected adults sh owed that 35% oi them would erase all at their personal lniomratioh online ii they could, Complete parts (a) and (b) below a. Express the original claim in symboliclorm. Let the parameter represent the adults that would erase their personal information V V (Type an integer or a decimal Do not round ) Claim: The mean pulse rate (in beats per minute) of adult males is equal to BE 9 bpm For a random sample of 129 adult males. the mean pulse rate is 69 B bpm and the standard deviation is 10.6 bpm. Complete parts (a) and [in] below. a. Express the original claim in symboliclorm. V V bpm (Type an integer or a decimal, Do not round ) Claim: The standard deviation of pulse rates of adult males is less than 11 bpm. For a random sample of 146 adult males, the pulse rates have a standard deviation of 10.4 bpm. Complete parts (a) and (b) below. a. Express the original claim in symbolic form. bpm (Type an integer or a decimal. Do not round.)\fMake a decision about the given claim. Use only the rare event rule, and make subjective estimates to determine whether events are likely. For example, if the claim is that a coin favors heads and sample results consist of 11 heads in 20 flips, conclude that there is not sufficient evidence to support the claim that the coin favors heads (because it is easy to get 11 heads in 20 flips by chance with a fair coin). Claim: The mean age of students in a large math class is greater than 20. A simple random sample of the students has a mean age of 34.4. Choose the correct answer below. O A. The sample is not unusual if the claim is true. The sample is unusual if the claim is false. Therefore, there is not sufficient evidence to support the claim. O B. The sample is not unusual if the claim is true. The sample is unusual if the claim is false. Therefore, there is sufficient evidence to support the claim. O C. The sample is unusual if the claim is true. The sample is not unusual if the claim is false. Therefore, there is not sufficient evidence to support the claim. O D. The sample is unusual if the claim is true. The sample is not unusual if the claim is false. Therefore, there is sufficient evidence to support the claim.Claim: Most adults would erase all of their personal information oane if they could, Asot'hvere rm surveyI of 560 randomly seleded adults showed that 55% of them woutd erase aH of their personal information online ifthey could Find the value of the test statistic. The value of the test statistic is . (Round to two decimal places as needed.)
