Rosters chicken advertises "lite" chicken with 30% fewer calories than standard chicken. when the process for "lite" chicken breast production is in control, the average chicken breast contains 430 calories, and the standard deviation in caloric content of the chicken breast population is 30 calories. rosters wants to design an x overbar-chart to monitor the caloric content of chicken breasts, where 25 chicken breasts would be chosen at random to form each sample. a) what are the lower and upper control limits for this chart if these limits are chosen to be four standard deviations from the target?

Lower control limit: 310

Upper control limit: 550

Step-by-step explanation:

The problem states that the average chicken breast contains 430 calories, and the standard deviation in caloric content of the chicken breast population is 30 calories.

a) What are the lower and upper control limits for this chart if these limits are chosen to be four standard deviations from the target?

The lower control limit is the mean subtracted by four standard deviations. So 430 - 4*30 = 310;

The upper control limit is the mean added four standard deviations. So 430 + 4*30 = 550;

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
