The records of a casualty insurance company show that, in the past, its clients have had a mean of 1.8 auto accidents per day with a standard deviation of 0.05. The actuaries of the company claim that the standard deviation of the number of accidents per day is no longer equal to 0.05. Suppose that we want to carry out a hypothesis test to see if there is support for the actuaries' claim. State the null hypothesis H, and the alternative hypothesis H, that we would use for this test. H, :0

- The records of a casualty insurance company show that, in the past, its clients have had a mean of 1.9 auto accidents per day with a variance of 0.0036. The actuaries of the company claim that the variance of thenumber of accidents per day is no longer equal to 0.0036. Suppose that we want to carry out a hypothesis test to see if there is support for the actuaries' claim.

A professor of statistics claims that her students take 45 minutes to complete her exams. You think that the average time is higher than that and decide to investigate using a significance level of 0.01. You take a random sample 20 of her statistics students and find that the students averaged 54 minutes to complete her exams, with a standard deviation of 15 minutes. Perform a hypothesis test. What is your p-value? Ho: H₁: P = L n= X = o or s = a= Illustrate the rejection region. which one is the claim? Which statistic will you use? Why? Will you use o or s? Why?A researcher is interested in seeing if the average income of rural families is less than that of urban families. To see if his claim is correct he randomly selects 23 families from a rural area and finds that they have an average income of $69963 with a standard deviation of $769. He then selects 23 families from a urban area and finds that they have an average income of $68783 with a standard deviation of $571. Perform a hypothesis test using a significance level of 0.05 to help him decide.Let the rural families be sample 1 and the urban families be sample 2.The correct hypotheses are:An independent consumer group published its finding that the lifetimes of electric bulbs manufactured by BIG Corporation are approximately normally distributed with a mean of 620 days and a standard deviation of 124.5. BIG Corporation claims that the standard deviation of its electric bulbs is less than 124.5. Suppose that we want to carry out a hypothesis test to see if BIG Corporation's claim is correct. State the null hypothesis H0, and the alternative hypothesis H1 that we would use for this test.

Ho: 0 H₁:0 3The price of a certain combo meal at different franchises of a national fast food company varies from $5.00 to $17.37 and has a known standard deviation of $2.02. A sample of 27 students in an online course that includes students across the country stated that their average price is $5.50. The students have also stated that they are generally unwilling to pay more than $6.25 for this meal. Formulate and conduct a hypothesis test to determine if you can conclude that the population mean is less than $6.25. Use a level of significance of 0 01 is there sufficient evidence at the 0.01 level of significance that the population mean is less than $6.25? Determine the null hypothesis, Ho, and the alternative hypothesis, H₁. Ho H₂ (Type integers or decimals. Do not round.)BIG Corporation advertises that its light bulbs have a mean lifetime, μ , of at least 3000 hours. Suppose that we have reason to doubt this claim and decide to do a statistical test of the claim. We choose a random sample of light bulbs manufactured by BIG and find that the mean lifetime for this sample is 2840 hours and that the sample standard deviation of the lifetimes is 700 hours. Based on this information, answer the questions below. What are the null hypothesis ( H0 ) and the alternative hypothesis ( H1 ) that should be used for the test?
