Important! Please answer! A new breath mint has a 30-minute infomercial. The company claims its mint lasts longer than the most popular mint. "In our research lab, we interviewed 10 of our happy customers. We asked them how much longer our mint lasted than others they have tried. On average, they estimated that our mint freshened breath 50% longer than other mints."

There are several issues with this research. Identify its weaknesses, and explain how you would redesign the study to fix those problems.

it is true

step-by-step explanation:

all the combinations add up i used   calculator

126 maybe. sorry

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
