Indicate whether CPAs in states that have flat state income tax rates work fewer hours per week during tax season compared to the US average. You will want to formally set up H0 and Ha, report either the test statistic (z-value) or p-value, and explain why you either reject or fail to reject your null hypothesis.
A sample of 100 flounder have a sample mean weight of 21.5 grams. Scientists wish to perform a hypothesis test to determine if the mean weight differs from 20 grams. State the appropriate null and alternative hypotheses.
A bank Manager developed a new System to reduce the time customers spend waiting for a teller service during peak hours. The Manager hopes that the new system will reduce the waiting time from the current 9 to 10 minutes to less than 6 minutes. Suppose that the Manager wishes to use the 100 waiting times to support the claim that the mean waiting time under new system is shorter than 6 minutes.a) Letting µ represent the mean waiting time under the new system, set up the null hypothesis and alternative hypothesis needed if we want to attempt to provide evidence supporting claim that µ is shorter than 6 minutes.b) In the context of this situation interpret making a type I error, interpret making a type II error.
A sample of 50 chewable vitamin tablets have a sample mean of 230 milligrams of vitamin C. Nutritionists want to perform a hypothesis test to determine how strong the evidence is that the mean mass of vitamin C per tablet exceeds 225 milligrams. State the appropriate null and alternative hypotheses.
the manager of an automobile dealership is considering a new bonus plan designed toincrease sales volume. currently, the mean sales volume is 14 automobiles per month. themanager wants to conduct a research study to see whether the new bonus plan increasessales volume. to collect data on the plan, a sample of sales personnel will be allowed tosell under the new bonus plan for a one-month period.a. develop the null and alternative hypotheses most appropriate for this situation
A sample of 60 chewable vitamin tablets have a sample mean of 298 milligrams of vitamin C. Nutritionists want to perform a hypothesis test to determine how strong the evidence is that the mean mass of vitamin C per tablet differs from 299 milligrams. State the appropriate null and alternate hypotheses.
As a result of complaints from customers about delivery times, the managerat a pizza delivery service is ready to undertake a study to determine the average delivery time. Until now, the manager has believed the delivery time was 20 minutes. What are the null and alternative hypotheses?
For the given scenario, determine the type of error that was made, if any. (Hint: Begin by determining the null and alternative hypotheses.) A radio station has accepted 2626 as the mean age of its listeners. One radio station executive claims that the mean age of its listeners is different from 2626. The radio station executive conducts a hypothesis test and rejects the null hypothesis. Assume that in reality, the mean age of its listeners is 2929. Was an error made? If so, what type?
The recommended dietary allowance (RDA) of vitamin C for women is 75 milligrams (mg) per day. A hypothesis test, with a significance level of 0.05, is to be performed to decide whether adult women are, on average, getting less than the RDA of 75 mg per day. A researcher gathers data from a random sample of women in order to carry out the test. Determine the Null and Alternative hypotheses.
A group of transfer bound students wondered if they will spend the same mean amount on texts and supplies each year at their four-year university as they have at their community college. They conducted a random survey of 54 students at their community college and 66 students at their local four-year university. The sample means were $947 and $1,011, respectively. The population standard deviations are known to be $254 and $87, respectively. Conduct a hypothesis test to determine if the means are statistically the same, using the same format as problem 2, Please only answer g-h. I submitted this once before and recieved answers for a-f.
