Which of the following accurately describes the chi-square test for goodness of fit? a. It is similar to a correlation because it uses one sample to evaluate the relationship between two variables. b. It is similar to both a correlation and an independent-measures t test because it can be used to evaluate a relationship between variables or a difference between populations. c. It is similar to an independent-measures t test because it uses separate samples to evaluate the difference between separate populations. d. It is similar to a single-sample t test because it uses one sample to test a hypothesis about one population.

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

it is 10.6 according to my calculations
