Abottle contains a label stating that it contains pills with SDI] 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 cements ofthe pills, which would have more serious implications: rejection of the vitamin C claim or rejection 0! the aspirin claim? Considering only a type i enor and using The same sample size. is it wise to use the same signicance level or hypothesis tests about the mean amount of vitamin C and the mean amount of aspirin? Rejection ol the claim about V is more serious because the wrong V dosage could cause more serious adverse reactions Than a wrong V dosage. It would be wise to use a V signicance level for testing The claim about the aspirin The test statistic of z = 1.2]Ir is obtained when testing the claim that p .2:- l].2. .1. Identify the hypothesis test as being haretailed, lefttailed, or righttailed. b. Find the Pvalue. c. Using a signicance level of o = [1.01, should we reject HD or should we fail to reject H\"?

The test statistic of z = 2.59 is obtained when testing the claim that p #0.229. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a = 0.10, should we reject Ho or should we fail to reject Ho? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. a. This is a test.The test statistic of z = - 2.40 is obtained when testing the claim that p I] 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 D 5. It you have an interest in establishing the success of the method. which at the loilowing Pvalues would you prefer 0.999.051.95' 0.05, 0.01. 0.001? Why? The P-value ol V is preferred because it. corresponds to the sample evidence that most strongly supports the V hypothesis that the method V effective. Claim: A minority of adults would erase all of their personal information online if they could. A software firm survey of 470 randomly selected adults showed that 35% of them would erase all of their personal information online if they could. Complete parts (a) and (b) below. a. Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information. (Type an integer or a decimal. Do not round.)Claim: The mean pulse rate (in beats per minute) of adult males is equal to 68.9 bpm. For a random sample of 129 adult males, the mean pulse rate is 69.8 bom and the standard deviation is 10.6 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.)Claim: The standard deviation of pulse rates of adult males is less than 11 bom. For a random sample of 146 adult males, the pulse rates have a standard deviation of 10.4 bom. Complete parts (a) and (b) below. a. Express the original claim in symbolic form. 1bpm (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 etaee all of their personal information online ifthey could. Asol'tware n'n survey of 560 randomly selected adults showed that 55% ofthem would erase all of their personal information online ifthey could. Find the value of the test statistic. The value of the test statistic is . (Round to M0 decimal places as needed.) Claim: The mean pulse rate (in beats per minute) of adult males is equal to 69 bpm For a random sample M154 adult mal. The mean pulse rate is 63.? bpm and the standard deviation is 11.1 bpm. Find the value of the test statistic. The value at the test statistic is . (Raund to two decimal places as needed )
