The following are the numbers of defective solder joints found during successive samples of 100 solder joints: Day No. of Defectives Day No. of Defectives 1 44 11 36 2 46 12 62 3 32 13 35 4 40 14 41 5 29 15 42 6 31 16 30 7 46 17 46 8 64 18 38 9 44 19 18 10 46 20 30 4 a. Using all the data, compute trial control limits for a fraction-defective control chart. (13 points) b. Determine whether the process is in statistical control. If the process is out of control, you do not need to construct revised control limits. (6 points)

pls refer ro the top for answer

step-by-step explanation:

the answer is 89 d

i took the test

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.

step-by-step explanation:

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
