Assume that last year in a particular state with 700000 children there were 1471 children out of 32500 in a random sample who were diagnosed with Autism Spectrum Disorder. Nationally, 1 out of 88 children are diagnosed with ASD. Is there sufficient data to show that the incident rate of ASD is higher in that state than nationally? Test at the 1% level.
A marriage counselor has traditionally seen that the proportion p of all married couples for whom her communication program can prevent divorce is 79%. After making some recent changes, the marriage counselor now claims that her program can prevent divorce in mot e than 79% of married couples. In a random sample of 225 married couples who completed her program, 194 of them stayed together. is there enougn evidence to suppore che marriage counselor's claim at the 0.10 level of sionificance:
Suppose that 25% of patients with MI in 2000 died within24 hours. This proportion is called the 24-hour case-fatalityrate. 7.14 Of the 15 new MI cases in the preceding study,5 died within 24 hours. Test whether the 24-hour casefatality rate changed from 2000 to 2010
Suppose the avg score on Midt1 is usually 78, and on Midt2 is 73. If your final grade is weighted 0.85 and 0.15 for Midt1 and Midt2, respectively, what is the expected final course grade? (i.e. what is E(a*Midt1 + b*Midt2)? (Please round to two decimal places: ex: 12.34)
The incidence of a certain type of chromosome defect inthe U.S. adult male population is believed to be 1 in 75.A random sample of 800 individuals in U.S. penal institutionsreveals 16 who have such defects. Can it be concludedthat the incidence rate of this defect among prisonersdiffers from the presumed rate for the entire adultmale population?
The police tested 550 people, to see if anyone would match the partial fingerprint at the crime scene. The probability of getting a false-positive result for a single person, was 0.3%. Using the same formula and method as shown in the video: What would be the new approximate percentage probability of getting at least one false-positive result, if 550 people are still tested, but the probability of getting a false-positive result for a single person was 0.4% instead of 0.3% ? (Assume all other aspects of the situation are the same as in the original problem, with the only change being the probability of getting a false-positive result for a single person.) Round to four digits past the decimal point, and include a percentage symbol in your answer (with no spaces).
A random sample of 25 tires gave the average life as 38000 km and S.D. as 5000 km. Can it be concluded that the sample is drawn from a population with a mean life of 40000 km?
An administrator at a rural college claims that the proportion, p, if students who commute farther than fifteen miles to school is more than 15%. To test this, she selects a random sample of 275 students at this college, and she finds that 42 commute father than fifteen miles to school, is there enough evidence to support the administrators claim at the 0.10 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table.
Suppose an experiment finds that people taking a new herbal remedy get fewer colds than people taking a placebo. The results are statistically significant at the 0.01 level. Has the experiment proven that the herbal remedy works?
1. Per the CDC article, men have higher blood pressure than women. Is this also true for this wholesale distribution center population? Use 0.05. Determine whether your (NEW) sample provides statistical evidence that this company’s population of adults has men with a higher blood pressure than women. Set alpha at 0.05 just focus on the Systolic number.
A certain financial services company uses surveys of adults age 18 and older to determine if personal financial fitness is changing over time. A recent sample of 1,000 adults showed 410 indicating that their financial security was more than fair. Suppose that just a year before, a sample of 700 adults showed 245 indicating that their financial security was more than fair. (a) State the hypotheses that can be used to test for a significant difference between the population proportions for the two years. (Let p1 = population proportion most recently saying financial security more than fair and p2 = population proportion from the year before saying financial security more than fair. Enter != for ≠ as needed.) H0: Ha: (b) Conduct the hypothesis test and compute the p-value. At a 0.05 level of significance, what is your conclusion? Find the value of the test statistic. (Use p1 − p2. Round your answer to two decimal places.) Find the p-value. (Round your answer to…
An administrator at a rural college claims that the proportion, p, if students who commute father than fifteen miles to school is more than 15%.
