To investigate an alleged unfair trade practice, the FTC takes a random sample of 16 "5-ounce" candy bars. The mean of the sample weights is 4.85 ounces, and the sample standard deviation is 0.1 ounce. Test the hypotheses: H0 : μ ≥μ≥ 5 Ha : μμ < 5 At the 5% significance level. Assume the population of candy bar weights is approximately normally distributed. Bases on the results, does the FTC have grounds to proceed against the manufacturer for unfair practice of short-weight selling?

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
