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?

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
