A six sigma green belt is performing a hypothesis test of two sample means. Sixteen samples of method A and sixteen samples of method B are produced. The standard deviations are unknown, but thought to be the same. How many degrees of freedom are to be used for the t test

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

- (2, -7)

- lines r and s and lines t and u must be parallel

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
