A soft drink vending machine, when in perfect adjustment, fills bottles with 12 ounces of soft drink. A random sample of 25 bottles is selected, and the contents are measured. The sample yielded a mean content of 11.88 ounces, with a sample standard deviation of 0.24 ounce. With a .05 level of significance, test to see if the machine is in perfect adjustment. Assume the distribution of the population is normal.

Group of answer choices

t = -2.5; therefore, reject H00. There is sufficient evidence at αα = .05 to conclude that the machine is NOT in perfect adjustment.

z = -2.5; therefore, reject H00. There is sufficient evidence at αα = .05 to conclude that the machine is NOT in perfect adjustment.

z = -2.5; therefore, do not reject H00. There is sufficient evidence at αα = .05 to conclude that the machine is NOT in perfect adjustment.

t = -2.5; therefore, do not reject H00. There is sufficient evidence at αα = .05 to conclude that the machine is NOT in perfect adjustment.

t = -2.5; therefore, reject H00. There is sufficient evidence at αα = .05 to conclude that the machine is in perfect adjustment.

    Design specification for a soft drink filling machine is to fill bottles with 12 ounces of soft drink. A random sample of 49 bottles filled by this machine was sampled and the contents measured. If this sample had a mean measurement of 11.9 ounces with a standard deviation of 0.28 ounces, is the machine really under-filling bottles? Test at a 5% significance level.

    A soft-drink vending machine can be regulated to ensure that it dispenses an average of 6 oz. of soft drink per glass. If the ounces dispensed per glass are normally distributed with a standard deviation of 0.3 oz., find the probability for a sample of 5 bottles, that the machine will average more then 6.3 ounces.

    A coffee vending machine is set to fill a cup with an average of 6.5 ounces of soft drink. The amount of fill varies. Sometimes the machine overfills the cup until it overflows and sometimes it fills it under the legal minimum. Suppose the amount of fill, X, follows the Normal distribution with an average of 6.5 ounces and a standard deviation of 0.3 ounces. What is the probability that a 7-ounce cup overflows, that is, find P(X>7)? Given the...

    A lathe is set to cut bars of steel into lengths of 6 cm. The lathe is considered to be in perfect adjustment if the average length of the bars it cuts is 6 cm. A sample of 121 bars is selected randomly and measured. It is determined that the average length of the bars in the sample is 6.08 cm. The population standard deviation is 0.44 cm. Determine whether or not the lathe is in perfect adjustment. Use a...

    A soft drink company produces bottles of cola that are supposed to contain 10 ounces. When the bottling machine is working correctly, the number of fluid ounces per bottle is in fact normally distributed with mean 10 ounces and standard deviation 0.42 ounces. A customer buys nine bottles of this type of cola. What is the probability that the average volume of cola in the nine bottles is more than 9.7 ounces but less than 10.2 ounces? (A) 0.9074 (B)...
