A company manufacturing oil seals wants to establish X and R control charts on the process. There are 25 preliminary samples of
alisha [4.7K]

Answer:

A ) i) X control chart : upper limit = 50.475, lower limit = 49.825

    ii) R control chart : upper limit =  1.191, lower limit = 0

Step-by-step explanation:

A) Finding the control limits

grand sample mean = 1253.75 / 25 = 50.15

mean range = 14.08 / 25 = 0.5632

Based on  X control CHART

The upper control limit ( UCL ) =

grand sample mean + A2* mean range ) = 50.15 + 0.577(0.5632) = 50.475

The lower control limit (LCL)=

grand sample mean - A2 *  mean range = 50.15 - 0.577(0.5632) = 49.825

Based on  R control charts

The upper limit = D4 * mean range = 2.114 * 0.5632 = 1.191

The lower control limit = D3 * mean range = 0 * 0.5632 = 0  

B) estimate the process mean and standard deviation

estimated process mean = 50.15 = grand sample mean

standard deviation = mean range / d2  = 0.5632 / 2.326 = 0.2421

note d2 is obtained from control table

A ruby-throated hummingbird beats it’s wings about 53 times each second.About how many times does a ruby-throated hummingbird be
Tcecarenko [31]
Well you take 53 per second and you multiply 53 by 5

53 x 5 = ?

50 x 5 = 250

3 x 5 = 15

So your exact answer is 265... I also am not sure where you want it rounded to but if it was a default "round" I would say 250

Write a short statement that expresses a possible relationship between the variables. Gas mileage of car, cost of driving 500 mi
PIT_PIT [208]

Answer:

D) As the gas mileage increases, the cost of driving a fixed distance increases.

Step-by-step explanation:

Hello!

Given the variables

X₁: Gas mileage of a car

X₂: Cost of driving 500 miles

Normally the variable that changes more is the gas mileage of the car, depending on the type of the car or the age of different cars from the same model and brand, the amount of gas used to cover a fixed distance varies.

From a logical point of view you'd expect that the more gas the car consumes, the more it will cost to drive a fixed distance. So the correct option is D)

Options:

A) As the gas mileage increases, the cost of driving a fixed distance decreases.

B) As the cost of driving a fixed distance increases, the gas mileage decreases.

C) As the cost of driving a fixed distance decreases, the gas mileage increases.

D) As the gas mileage increases, the cost of driving a fixed distance increases.

I hope this helps!
