I feel like the answer might be around 6.38, but I’m not completely confident. I hope I remember the right formula for calculating the mean!

I practiced a question like this where we had to find the mean from grouped data. I think it involves using the midpoints, but I can't recall the exact steps.

I think the arithmetic mean is found by dividing the total number of customers by the number of months, right? But I’m a bit confused about how to handle the grouped data.

I remember we calculated the mean in a similar question, but I’m not sure if I should sum the frequencies first or just the midpoints.

Hmm, this seems like a tricky one. I'll need to think through the different options carefully.

I've got a good feeling about this one. The details are pretty comprehensive, so I think if I can break it down and tackle each part systematically, I should be able to work through this successfully.

I think the departmental secretary might not be exempt since they do a lot of clerical tasks, but I'm not completely clear on the specifics about administrative roles.

This seems straightforward enough. I'll review the options and choose the one that best matches the requirements of mirroring the disks and adding the flash devices as cache.
