The postal service sorts mail as Priority Mail Express, Priority Mail, First-Class Mail, or Standard Mail. Over a period of 3 weeks, 18 of each type were mailed from the Network Distribution Center in Atlanta, Georgia, to Des Moines, Iowa. The total delivery time in days was recorded. Minitab was used to perform the ANOVA.

Hurricane Andrew swept through southern Florida causing billions of dollars of damage. Because of the severity of the storm and the type of residential construction used in this semitropical area, there was some concern that the average claim size would be greater than the historical average hurricane claim of $23,000$⁢23,000. Several insurance companies collaborated in a data gathering experiment. They randomly selected 2222 homes and sent adjusters to settle the claims. In the sample of 2222 homes, the average claim was $24,500$⁢24,500 with a population standard deviation of $4100$⁢4100. Is there sufficient evidence at a 0.010.01 significance level to support the claim that the home damage is greater than the historical average? Assume the population of insurance claims is approximately normally distributed. Compute the value of the test statistic. Round your answer to two decimal places.
A university dean is interested in determining the proportion of students who recieve some sor of financial aid. Rather than examine the records for all students, the dean randomly selects 200 students and finds that 118 of them are receiving financial aid. If the dean wanted to estimate the proportion of all students receiving financial aid to within 4% with 90% reliabilty, how many students would need to be sampled?

Because of the increased cost of housing, a national real estate board wants to comparethe proportion of homeowners living in metropolitan areas with the proportion living inrural areas. The board members know that housing costs are higher in metropolitanareas, but they also know that small town and rural residents have substantially lowerincome levels. The board has decided to find out whether the corresponding proportionsdiffer from one another. A random sample of 150 persons living in rural areas contains93 homeowners, while a sample of 225 persons living in metropolitan areas has 126homeowners.a). At 5% level of significance, is there evidence to support the board’s intention? Yourconclusion must be in terms of the P-Value. Show all necessary work. b).

In a major urban area, the percentage of male drivers between the ages of 19 and 29 who did not regularly use seatbelts was 28%. After a major radio and television campaign and stricter enforcement by the local police, researchers want to know if the percentage of male drivers between the ages of 19 and 29 who did not regularly use seatbelts has decreased. They poll a random sample of 100 males between the ages of 19 and 29 and find the percentage who didn’t wear their seatbelt was 24%. (a) Identify the population, parameter, sample and statistic.(b) State appropriate hypotheses for performing a significance test.

An LED light bulb manufacturer claims that the average lifespan of its 60-watt LED light bulbs is 43,000 hours.A corporate watchdog group is suspicious of the company's claim and thinks that the true average lifespan of the 60-watt LED light bulbs produced by the company may be less than the advertised 43,000 hours. The group collected and tested a random sample of 240 light bulbs and found the average lifespan of the sample was 42,958 hours.Use the p-value method to test the hypothesis that the mean lifespan of this brand of 60-watt LED light bulb is less than 43,000 hours, using α=0.025α=0.025. Assume the standard deviation of the lifespan of all such light bulbs is known to be 430 hours.State the null and alternative hypothesis for this test.H0:H0: H1:H1: Determine if this test is left-tailed, right-tailed, or two-tailed. right-tailed two-tailed left-tailed Should the standard normal (zz) distribution or Student's (tt) distribution be used for this…
