Flying time on an old route between 2 cities has a mean value of =5.25 hours...

Flying time on an old route between 2 cities has a mean value of =5.25 hours with standard deviation is =0.6 hours. There are 36 flights on a new route where the mean is hours. Does this indicate that the average flying time for the new route is less than 5.25 hours? Use a 5% level of significance.

  1. State the null and alternate hypothesis.
  2. Will you use a left tail, right tail or 2 tailed test?
  3. Identify the sampling distribution to be used: standard normal, Student’s t or chi squared.
  4. Find the value of the test statistic.
  5. Find the P-Value.
  6. Based on your answers, shall we reject or accept the null hypothesis?
  7. Write the conclusion in the context of the problem.

A systems specialist has studied the workflow of clerks all doing the same inventory work. Based on this study, she designed a new workflow layout for the inventory system. To compare the average production for the old and new methods, a random sample of 6 clerks was used. The average production rate (number of inventory items processed) for each clerk was measures both before and after the new system was introduced. The results are shown below. Test the claim that...

Using traditional methods it takes 106 hours to receive an advanced flying license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 40 students and observed that they had a mean of 105 hours. Assume the population standard deviation is known to be 4. Is there evidence at the 0.02 level that the technique reduces the training time? Step 1 of 6: State the null and alternative hypotheses. Step 2 of...

A new bus route has been established between downtown Denver and Englewood (a suburb of Denver). Eric has taken the bus to work for many years. For the old bus route, he knows from long experience that the mean waiting time between buses at his stop was 20 minutes. However, a random sample of 34 waiting times between buses using the new route had a mean of 17.2 minutes with a sample standard deviation of 6.4 minutes. Does this indicate...

Using traditional methods it takes 91 hours to receive an advanced flying license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 70 students and observed that they had a mean of 92 hours. Assume the population variance is known to be 25. Is there evidence at the 0.02 level that the technique lengthens the training time? Step 1 of 6: State the null and alternative hypotheses. Step 2 of 6:...

Using traditional methods it takes 101 hours to receive an advanced flying license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 160 students and observed that they had a mean of 100 hours. Assume the population standard deviation is known to be 6 . Is there evidence at the 0.02 level that the technique performs differently than the traditional method? Step 1 of 6: State the null and alternative hypotheses....

Using traditional methods it takes 8.7 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 12 students and observed that they had a mean of 8.5 hours with a standard deviation of 1.1. Is there evidence at the 0.05 level that the technique performs differently than the traditional method? Assume the population distribution is approximately normal. Step 1 of 5: State the null...

he mean age of graduate students at a University is thought to be 31 years old. A random sample of 15 graduate students is taken. The sample mean age is 33 years and the sample standard deviation is three years. Does the sample data indicate that the population mean age is actually greater than 31 years old? Use a 1% level of significance. a.) What is α? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or...

Suppose that an airline quotes a flight time of 2 hours, 10 minutes between two cities. Furthermore, suppose that historical flight records indicate that the actual flight time between the two cities, x, is uniformly distributed between 2 hours and 2 hours, 20 minutes. Letting the time unit be one minute, (a) Calculate the mean flight time and the standard deviation of the flight time. (Round your answers to 4 decimal places.) μx σx (b) Find the probability that the...

Using traditional methods it takes 11.411.4 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 2424 students and observed that they had a mean of 11.211.2 hours with a standard deviation of 1.41.4. Is there evidence at the 0.10.1 level that the technique reduces the training time? Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis....
