A rare and deadly disease has a disease rate of 0.1%. A screening test of the disease called DT is good in the sense that the accuracy of the test among healthy people is 97%, while the accuracy among diseased people is 99%. What is the overall accuracy of the test DT? Further, if a friend of yours diagnosed positively, what is the chance that he (she) really don’t have the disease?

OBFW Publishers A state's Division of Motor Vehicles (DMV) claims that 60% of all teens pass their driving test on the first attempt. An investigative reporter examines an SRS of the DMV records for 125 teens; 86 of them passed the test on their first try. A hypothesis test of Ho: P = 0.60 Ha:p # 0.60 where p = the true proportion of teens who pass their driving test on the first attempt using a = 0.05 gives a P-value of 0.0444. A 95% confidence interval for the true proportion of teens who pass the driving test on the first attempt is 0.607 to 0.769. Which is the following statements is not true with regards to the 95% confidence interval provided and the result of the hypothesis test? OA two-sided test only allows us to reject (or fail to reject) a hypothesized value for a particular population parameter. The value 0.60 is not a plausible value because it falls outside the 95% confidence interval. The 95% confidence interval provided gives an approximate set of po's that would not be…
IQ tests are approximately normally distributed with a mean of 100 for adults. A tech company CEO wants to conduct a hypothesis test to see if the average IQ of employees at high-tech firms in California is higher than average. What is Type I error in the context of this problem?

Mark performed a two-sample z-test for proportions to test the hypothesis that there was no difference in the proportion who support increasing student fees between male and female students at a particular university. Mark obtained a z-statistic of 0. Based on this information, which of the following is always true. The sample proportions for male and females will be the same as the hypothesized proportions for male and female students at this university. The sample proportions for both male and female students at this university will be 0. All male and female students in the sample will feel the same way about supporting the increase in student fees. The sample proportions will be the same for both male and female students at this university. Test whether p1>p2 The sample data are x1=116,n1=258,x2=135,n2=311.

Fear of the dark is quite common among children. However, what about adults? One polling agency released the results of a survey that asked people over 30 years old if they keep the lights on at night. Among 452 respondents, 34% indeed leave the light on when going to sleep. What does this margin of error tell you about the percentage of adults who keep the lights on at night? We can be 95% confident that somewhere between % and % of adults keep the lights on at night.
