Suppose that it is known that 2.4% of patients taking competing drugs complain of flulike symptoms. symptoms as a side effect at the a=0.01 level of significance? there sufficient evidence to conclude that more than 2.4% of this drug's users experience flulike Because npo (1-Po) =O v 10, the sample size is (Round to one decimal place as neoded.)

- In a clinical trial, 27 out of 875 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.6% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.6% of this drug's users experience flulike symptoms as a side effect at the a = 0.01 level of significance? Họ: P = 0.026 versus H,: p 0.026 (Type integers or decimals. Do not round.) Find the test statistic, zo. zo = |(Round to two decimal places as needed.)In an observational study it was found that people who had received the flu shot this year had better blood pressure readings, on average, than people who did not. Can it be claimed that the flu shot is the cause of the lower overall blood pressure? Why or why not?According to a certain government agency for a large country, the proportion of fatal traffic accidents in the country in which the driver had a positive blood alcohol concentration (BAC) is 0.34. Suppose a random sample of 106 traffic fatalities in a certain region results in 48 that involved a positive BAC. Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the a= 0.01 level of significance? .... Because npo (1- Po) =| 10, the sample size is 5% of the population size, and the sample the requirements for testing the hypothesis satisfied. (Round to one decimal place as needed.)

- In a study conducted by the U.S. Department of Health and Human Services, a sample of 546 boys aged 6–11 was weighed, and it was determined that 87 of them were overweight. A sample of 508 girls aged 6–11 was also weighed, and 74 of them were overweight. Can you conclude that the proportion of boys who are overweight differs from the proportion of girls who are overweight? Please show calculIn a clinical trial, 29 out of 853 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.9% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.9% of this drug's users experience flulike symptoms as a side effect at the α=0.1 What is the test statistic z0?Consider a proposed case-control study of autism spectrum disorder (ASD) and maternal boba tea consumption in Irvine. Assume that 20% of Irvine mothers are regular consumers (at least 3 servings per week) of boba tea, and that the prevalence of ASD is 1/59 (making it a somewhat rare disease). Also assume that 50% of Irvine mothers who regularly consume boba tea prefer black milk tea, that the prevalence of regular boba tea consumption among mothers of autistic children is 25%, that each participant will be paid $30 to join the study, and that there are at least 1,000 mothers of autistic children and at least 100,000 mothers of non-autistic children in Irvine who are willing to participate in the study if compensated. If these assumptions are correct, what is the odds ratio describing the association between regular boba tea consumption and ASD? HINT: Recall that the disease odds ratio is equal to the exposure odds ratio.

Is there sufficient evidence to conclude that more than 2.9% of this drug's users experience flulike symptoms as a side effect at the α=0.1 level of significance. What is the P-value?Landolt et al. (A-26) examined rates of posttraumatic stress disorder (PTSD) in mothers and fathers. Parents were interviewed 5 to 6 weeks after an accident or a new diagnosis of cancer or diabetes mellitus type I for their child. Twenty-eight of the 175 fathers interviewed and 43 of the 180 mothers interviewed met the criteria for current PTSD. Is there sufficient evidence for us to conclude that fathers are less likely to develop PTSD than mothers when a child is traumatized by an accident, cancer diagnosis, or diabetes diagnosis? Let alpha = 0.05Apple, Inc. reported that "0.5% (0.005) of participants received irregular pulse notifications indicative of possible AFib" which is a dangerous heart condition that needs an immediate trip to the emergency room. To improve benefits of pulse notifications, it is important to identify the percentage of people receiving false notifications. A cardiologist is concerned that the percentage of people who actually have these types of irregular heartbeats is not accurate. The doctor randomly selected a simple random sample of 2315 adults who own Apple watches and asked if they have received one of these irregular heartbeat notifications. Nine of the respondents reported receiving such a notification. Does this evidence support the cardiologists claim that the percentage of people who receive notifications of irregular heartbeats is not 0.5% (0.005)? Can the conditions for the 1-proportion Z- test be met? No, normality cannot be met. Yes, all conditions are met. No, some part of the binomial…
- A researcher suspects that the actual prevalence of generalized anxiety among children and adolscents is higher than the previously reported prevalence of generalized anxiety disorder among children and adolescents. The previously reported prevalance of generalized anxiety disorder among children and adolescents is 3.9% and the researcher conducts a study to test the accuracy of the previously reported prevalence of generalized anxiety disorder by recruiting 98 children and adolescents from various pediatricians' offices and tests them for generalized anxiety disorder using the DSM-5. The researcher determines that the prevalence of generalized anxiety disorder among among the participants of the study is 6.1%. The researcher's hypothesis for a level of significance of 5%, should resemble which of the following set of hypothesis? A) H0: p>.039; H1p=.039; alpha= .05 B) H0: p=.039; H1 p>.039; alpha= .05 C)H0: p> .039 H1 p=.039; alpha=.95 D) H0: p=.039; H1 p>.039; alpha =.95A new drug to treat psoriasis has been developed and is in clinical testing.
