A new material is being tested for use in the manufacture of electrical conduit, to determine whether it will reduce the variance in crushing strength over the old material. Crushing strengths are measured for a sample of size 16 of the old material and a sample of size 20 of the new material. If it is shown that the crushing strength with the new material has smaller variance, the new material will be used.
A manufacturer of salad dressings uses machines to dispense liquid ingredients into bottles that move along a filling line. The machine works properly when 24.12 ounces of liquids are dispensed. Suppose that the average amount dispensed in a particular sample of 41 bottles is 20.65 ounces with a variance of 1.48 ounces squared. What is the test statistic to test the null hypothesis that the salad dressings machine dispenses 24.12 ounces of liquid ingredients against the alternative that the salad dressings machine dispenses liquid ingredients other than 24.12 ounces?
In a comparison between the mean waiting time of the patients in the hospitals of Giza and Alexandria governments the minister of Health randomly selected 60 hospitals from Giza government and their mean waiting time was 30 minutes and the previous reports showed that the variance was 10 minutes. Also a sample consist of 50 hospitals from Alexandria governments was selected and their mean waiting time of this sample was 15 minutes and from previous reports the variance was 5 minutes. 1-Construct the 95% C.I for the difference between the average waiting time in Giza & Alex2- Without any computations, discuss fully and precisely what will happen to the results you obtained in part (1) if the confidence level changed to be 99% instead of 95%.

A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.25. A dietician is asked to test this claim and finds that a random sample of 22 servings has a variance of 1.35. At ⍶ = 0.05 is there enough evidence to reject the manufacturer’s claim?
A manufacturer of salad dressings uses machines to dispense liquid ingredients into bottles that move along a filling line. The machine that dispenses salad dressings is working properly when 8 ounces are dispensed. Suppose that the average amount dispensed in a particular sample of 35 bottles is 7.91 ounces with a variance of 0.03 ounces squared. Is there evidence that the machine should be stopped and production wait for repairs? The lost production from a shutdown is potentially so great that management feels that the level of significance in the analysis should be 99%. (solve without excel)

A lumber company is making boards that are 29432943 millimeters tall. If the boards are too long they must be trimmed, and if they are too short they cannot be used. A sample of 1414 boards is made, and it is found that they have a mean of 2940.52940.5 millimeters with a variance of 144144. Is there evidence at the 0.0250.025 level that the boards are too short and unusable? State the null and alternative hypotheses for the above scenario.
The manager of Cines California affirms that the average duration oftype A comedy films exceed the average length oftype B horror movies in at least 15 minutes. Paracaverify this claim, 15 films of each type are testedunder similar conditions, obtaining that the film ofType A comedy has an average duration of 86.7 minuteswith a variance of 36 minutes, while the film ofType B terror has an average duration of 77.8 minutes with a25 minute variance. Test the manager's claim with theuse of a level of 0.01
A soft-drink dispensing machine is said to be out of control if the variance of the contents exceeds 1.15 deciliters. If a random sample of 25 drinks from this machine has a variance of 2.03 deciliters, does this indicate at the 0.05 level of significance that the machine is out of control? Assume that the contents are approximately normallyy distributed.

Below you are given the results of samples taken from domestic and International customers. Customers Domestic International s 155 95 n 25 20 At a = 0.05 level of significance, test to see if the variance of the Internationl customers is significantly more than the variance of Domestic Customers.
The average travel time going from Bulacan to Laguna is at most 3.5 hours. A bus company conducts a study consisting of 55 trials to verify this. Results show that on the average, the travel time from Bulacan to Laquna is 4.2 hours with a variance of 6.76 squared hours. Assume that the level of significance is 0.01.
Two processes for manufacturing large roller bearings are under study. In both cases, the diameters (in centimeters) are being examined. A random sample of 21 roller bearings from the old manufacturing process showed the sample variance of diameters to be s2 = 0.235. Another random sample of 26 roller bearings from the new manufacturing process showed the sample variance of their diameters to be s2 = 0.128. Use a 5% level of significance to test the claim that there is a difference (either way) in the population variances between the old and new manufacturing processes.
