A cola-dispensing machine is set to dispense 8 ounces of cola per cup, with a standard deviation of 1.0 ounce. The manufacturer of the machine would like to set the control limit in such a way that, for samples of 34, 5% of the sample means will be greater than the upper control limit, and 5% of the sample means will be less than the lower control limit.

At what value should the control limit be set? (Round z values to two decimal places. Round your answers to 2 decimal places.)
If the population mean shifts to 7.6, what is the probability that the change will not be detected? (Round your intermediate calculations to 2 decimal places and final answer to 4 decimal places.)
If the population mean shifts to 8.7, what is the probability that the change will not be detected? (Round your intermediate calculations to 2 decimal places and final answer to 4 decimal places.)

A cola-dispensing machine is set to dispense 10 ounces of cola per cup, with a standard deviation of 0.8 ounce. The manufacturer of the machine would like to set the control limit in such a way that, for samples of 31, 5% of the sample means will be greater than the upper control limit, and 5% of the sample means will be less than the lower control limit. At what value should the control limit be set? (Round z values...

A coffee machine is supposed to dispense 8 ounces (oz) of coffee into a paper cup....

A coffee machine is supposed to dispense 8 ounces (oz) of coffee into a paper cup. In reality, the amounts dispensed vary from cup to cup. However, if the machine is working properly, the standard deviation of the amounts dispensed should be less than 0.3/0.4/0.5 oz. To test this, a random sample of 10/15/20 cups was taken, and it give a standard deviation of 0.255 oz. a) At the 5% significance level, do the data provide sufficient evidence to conclude...

A soda vending machine is supposed to dispense 7 fluid ounces of soda into a cup....

A soda vending machine is supposed to dispense 7 fluid ounces of soda into a cup. The canteen manager tested the machine by taking a sample of 20 cups of soda. He measured the 20 cups of soda individually and found that the measurements had a mean of 8.08 fl. oz. and a standard deviation of 2.85 fl. oz. Determine if the machine dispense is different from the required ounces set by the company. (a) State the null hypothesis and...

A manufacturing company claims that its machines dispense, on average, 7 ounces per cup with a...

A manufacturing company claims that its machines dispense, on average, 7 ounces per cup with a standard deviation of 0.15 ounces. A consumer is skeptical of this claim, believing that the mean amount dispensed is less than 7 ounces. A sample of size 100 is chosen, which yields the average amount per cup: 6.6 ounces, what conclusions can be drawn? State the null and alternative hypotheses, and compute the P–value to justify your answer.

A soft-drink machine is regulated so that it discharges an average of 6.8 ounces per cup. If the amount of drink is normally distributed with a standard deviation equal to 0.5 ounces, Part a: What is the probability that a cup will contain more than 7.72 ounces? Part b: What is the probability that a cup contains between 6.72 and 7.06 ounces? Part c: How many cups will overflow if 7.8-ounce cups are used for the next 1000 drinks? Part...

A soft-drink machine is regulated so that it discharges an average of 6.6 ounces per cup. The amount of drink is normally distributed with a standard deviation equal to 0.5 ounces. Part 1: (3 points ) What is the probability that a cup will contain more than 7.54 ounces? Part 2: (3 points ) What is the probability that a cup contains between 6.54 and 7.06 ounces? Part 3: (4 points ) Suppose we want to regulate this machine so that only...

Coca-Cola years ago was experimenting with a vending machine that would dispense their products according to the weather, specifically the ambient air temperature. Also considered was whether the product was demanded during off season when there is less traffic. In one study, assuming 200,000 “smart” vending machines were in place, the incremental (marginal) profit associated with the smart vending machine was estimated at $328.5 million per year. In fact, the CEO of Coca-Cola was quoted as stating “In a final...

A vending machine dispenses coffee. The average cup of coffee is supposed to contain 7.0 ounces. Eight cups of coffee from this machine show the average content to be 7.3 ounces with a standard deviation of 0.5 ounce. Using a 5% level of significance, test whether the machine has slipped out of adjustment and if the average amount of coffee per cup is different from 7 ounces. Determine the p-value and interpret the results

A coffee machine dispenses 6 fluid ounces of coffee into a paper cup. Previous studies have shown that the amount dispensed is a normal distribution. A random sample of 15 cups is obtained where the standard deviation, s, is 0.154. Determine if the requirements are met to compute a confidence interval for the true standard deviation, σ, of amounts of coffee being dispensed. List each requirement and state information given to support each one. If the requirements are met, use...

Question # 1:A dispensing machine is set to produce 1 pound lots of a particular compound. The machine is fairly accurate, producing mean weight of lots equal to 1.0 pound with a standard deviation of 0.12 pounds. Thirty five lots are randomly selected: (a)What is the mean weight of the sample mean of the thirty five randomly selected lots? (b)What is the standard deviation of weight of the sample mean of the thirty five randomly selected lots? (c)Find the probability...
