A machine used to fill gallon-sized paint cans is regulated so that the amount of paint dispensed has a mean of
128
ounces and a standard deviation of
0.40
ounce. You randomly select
35
cans and carefully measure the contents. The sample mean of the cans is
127.9127.9
ounces. Does the machine need to be reset? Explain your reasoning.
▼
Yes
No
, it is
▼
very unlikely

that you would have randomly sampled
3535
cans with a mean equal to
127.9127.9
ounces, because it

lies
does not lie
within the range of a usual event, namely within

1 standard deviation
2 standard deviations
3 standard deviations
of the mean of the sample mean

A paint manufacturer uses a machine toll gallon cars with paint (1 128 ounces). The manufacturer wants to estimate the mean volume of paint the machine is puting in the card within 0.5 ounce Assume the population of volumes is normally distribuid. (8) Determine the minimum sample size required to constructa 90% confidence interval for the population mean.

5. Problem 5: A bottling machine can be regulated so that it discharges an average of pi ounces per bottle. It has been observed that the amount of fill dispensed by the machine is normally distributed with a = 1 ounce. A sample of n = 9 filled bottles is randomly selected from the output of the machine on a given day, and the ounces of fill are measured for each. Find the probability that the sample mean will be...

A machine set to fill soup cans with a mean of 20 ounces and a standard deviation of 0.1 ounces. A random sample of 34 cans has a mean of 20.02 ounces. Should the machine be reset? No, the probability of this outcome at 0.122, would be considered usual, so there is no problem No the probability of this outcome at 0.421 would be considered usual, so there is no problem Yes, the probability of this outcome at 0.878 would...

the amount dispensed by a canning machine into each can of beans, y is normally distributed with a mean of 14 ounces and a standard deviation of .12 ounce. Suppose we take a random sample of 20 cans filled by this machine. find the probability that the sum of amounts dispensed into the 20 cans is between 279 and 281 ounces

Question 1 The average math SAT score is 511with a standard deviation of 119. A particular high school claims that its students have unusually high math SAT scores. A random sample of 50 students from this school was selected, and the mean math SAT score was 555. Is the high school justified in its claim? Explain. ▼ Pick one No Yes because the z-score (what is the z score) (?) is ▼ pick one not unusual unusual since it ▼...
