Harold took five different samples of thirty-five randomly selected students from the 520 students he surveyed. The means of the samples are shown below. Sample Mean Sample 1 3. 4 Sample 2 3. 2 Sample 3 4. 1 Sample 4 4. 6 Sample 5 3. 1 The predicted mean of the population will fall between 3. 1 and . 1. 5 3. 4 3. 7 4. 6.

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!

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y

the five is the numerator
