Final Conclusions. In Exercises 25–28, use a significance level of α = 0.05 and use the given information for the following:
a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.)
b. Without using technical terms or symbols, state a Final conclusion that addresses the original claim.
27. Original claim: The mean pulse rate (in beats per minute) of adult males is 72 bpm. The hypothesis test results in a P-value of 0.0095.

- Final Conclusions. In Exercises 25–28, use a significance level of α = 0.05 and use the given information for the following: a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject h0). b. Without using technical terms or symbols, state a final conclusion that addresses the original claim. Original claim: Fewer than 90% of adults have a cell phone. The hypothesis test results in a p-value of 0.0003.arrow_forwardDetermine whether the standardized test statistic t indicates that you should reject null hypothesis. Explain a. T=1.506 b. t=0 c. T=-1.368 d. T=-1.483arrow_forwardThe table below shows results from a recent General Social Survey on two variables, respondent sex and whether one believes in an afterlife. Compare the proportions of women and men who believe in an afterlife. Question: State the hypotheses, calculate the test statistic, p-value and write your conclusions, using α = 0.05. Belief in Afterlife Sex Yes No or Undecided Total 1. Male 375 134 509 2. Female 435 147 582 Let = 1. be the population proportion of men who believe in an afterlife Let = 2. be the population proportion of women who believe in an afterlifearrow_forward
- From the table on the image: Construct an appropriate hypothesis test to determine whether or not there is an association between experiencing phenomena such as seeing a ghost and the age group you are in. Write the appropriate null/alternative hypothesis and carry out the test. Use a significance level of α = 0.01.arrow_forwardWe want to determine if the true proportion of students who do aerobics is less than 45%. Which are the correct hypotheses? Ho: P = 0.45; Ha: P≠ 0.45 Ho: P = 0.45; Ha: P > 0.45 Ho: P ≥ 0.45; Ha:P < 0.45 Ho: μ ≥ 0.45; Ha: μ < 0.45arrow_forwardAccording to a report on consumer fraud and identity theft, 21% of all complaints for a year were for identity theft. In that year, Ohio had 273 complaints of identity theft out of 1405 consumer complaints. Does this data provide enough evidence to show that Ohio had a lower proportion of identity theft than 21%? Test at the 1% level. State the hypotheses. Ho: P = v or .21 Ha: parrow_forwardIn a hypothesis test, H0 is p < 0.45 and Ha is p > 0.45. If the test statistic is z = 1.68, what is the P-value? Draw picture and give P-value only. Do not do rest of testing.arrow_forwardII. Conduct a hypothesis test A research center claims that less than 50% of senior high school students in public schools in the Philippines have accessed the Internet using cellular phones. In a random sample of 100 SHS students, 39% say they have accessed the Internet using cellular phones. At = 0.01, is there enough evidence to support the researcher's claim?arrow_forwardFinal Conclusions. In Exercises 25–28, use a significance level of α = 0.05 and use the given information for the following: a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0) b. Without using technical terms or symbols, state a final conclusion that addresses the original claim. Original claim: More than 58% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.3257.arrow_forwardarrow_back_iosarrow_forward_ios
