You wish to test the following claim (H) at a significance level of a = 0.05. You believe the population is normally distributed, but you do not know the standard deviation. You obtain a
sample of size = 424 with a mean of M = 33.1 and a standard deviation of SD = 8.6.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
