Wait, are we sure about those numbers? Seems off.

The total number of new customers is crucial for this calculation.

I think I might lean towards option C, but I’m not entirely confident. I hope I remember the steps correctly!

I’m a bit confused about how to handle the grouped data. Do I need to find the midpoint for each group before calculating the mean?

This question feels similar to one we did in class about customer data. I think the mean is found by dividing the total by the number of months.

I remember we practiced calculating the mean, but I’m not sure if I should sum the frequencies first or just the midpoints.

Wait, is the frequency the number of months in each range? Or is it the number of times that range occurred? I'm a bit confused about how to interpret this data.

Okay, I think I've got this. I'll multiply the midpoint of each range by the frequency, add those up, and then divide by the total number of months.

Hmm, I'm not sure how to handle the grouped data. Do I need to find the midpoint of each range and then calculate the mean?

This looks like a straightforward calculation of the arithmetic mean. I'll need to add up the number of new customers and divide by the total number of months.

D) 8.50 has to be the answer. I mean, come on, who doesn't love a good 8.50 new customers per month? That's the kind of growth any business would dream of!

This is a piece of cake! C) 6.38 is clearly the correct answer. Although, I do wonder if the CEO eats cake every month to celebrate the new customers... Mmm, cake.

I'm not sure, but I think the arithmetic mean is calculated by adding all the numbers and dividing by the total count. So, I would go with B) 6.50.

B) 6.50 seems like the right answer to me. The data shows a range of values, so 6.50 is a reasonable estimate of the mean.

I think 6.50 is the best choice based on the range of values shown in the data.

Yeah, the data is spread out, so 6.50 makes sense as the average.

The correct answer is C) 6.38. I calculated the total number of new customers (77) and divided by the number of months (12) to get the arithmetic mean.
