An axial load of an aluminum can is the maximum weight that the sides can support before collapsing. Pepsi experimented with thinner aluminum cans, and a random sample of 175 of the thinner cans had a mean axial load of 267.11 lb. Use a 0.01 significance level to test the claim that the thinner cans have a mean axial load that is less than 271.81 lb. Assume that σ = 27.77 lb

Is the mean weight of regular Coke less than the mean weight of regular Pepsi? To test this claim, independent sets of cans of each brand were selected for testing. The sample statistics are summarized in the table below. The distributions of weights of regular Coke and regular Pepsi are approximately normal, and population variances are not equal. At the 5% significance level, what is the appropriate conclusion? a) Reject the null hypothesis; reject the claim that the mean weight...

A company claims that a new manufacturing process changes the mean amount of aluminum needed for cans and therefore changes the weight. Independent random samples of aluminum cans made by the old process and the new process are taken. The summary statistics are given below. Is there evidence at the 5% significance level (or 95% confidence level) to support the claim that the mean weight for all old cans is different than the mean weight for all new cans? Justify...

5. a) Determine the maximum axial load the member shown can support before you would expect it to yield. The structure is made of A36 steel. The thickness of the structure is 2.0 in., the larger width is 12.0 in., and the smaller width is 8.0in. The fillet radius is 0.5in. b) A 35 ksi axial stress is applied to the beam cyclically (repeatedly applied then removed). How many times can this be done before you would expect the part...

The health of employees is monitored by periodically weighing them in. A sample of n = 54 employees has a mean weight of x̄ = 190 lb. Assuming that σ = 25 lb, use a 0.01 significance level to test the claim that the population mean of all such employees weights is less than 200 lb. Group of answer choices a. H0: μ = 200; H1: μ < 200; Test statistic: z = -2.94. P-value: 0.0016. Since the P-Value is...

Researchers studied the compression strength in lbs of 12-oz aluminum cans. A simple random sample of 35 aluminum cans filled with cola (which has more carbonation) had a sample mean compression strength of 554 lbs and a sample standard deviation of 15 lbs. A simple random sample of 30 aluminum cans filled with strawberry soda had a sample mean compression strength of 540 lbs and a sample standard deviation of 21 lbs. At the 0.05 significance level, perform a hypothesis...

Q 3. For constructing a parkway (no trucks allowed), engineers need weights of cars for which the parkway is to be designed, to ensure a safe road. A simple random sample of 32 cars yields a mean of 3605.3 lb (pounds) with a standard deviation of 501.7 lb. Use a 0.01 significance level to test the claim that mean weight of cars is less than 3700 lb. Q 4. From the data in Q 3, use a 0.01 significance level...
