Thank you 
I was also hoping to get help with this question please

The estimate for the area under the curve just comes from summing the areas of each rectangle. So, use the scales on the axes to get the widths and heights, find the areas, and add em up

Edit:

All you need to do here is to add the areas of the rectangles

When I added all the areas of the rectangles I got 9 sq units but the ans says ~8.7 sq units?

You will need to provide the information under that text.

The solution is under the text.

If that's all the information provided I actually don't see how we've been given enough information to do it. The "nominal length" isn't specified and we don't know what the true mean is, so this question reads like nonsense. Please provide the solution.

Here's the solution

Here's the solution

See, based off the information you had provided I have no idea how they got 1.8 or 1.85. So unless this question had a previous part to it, it was severely lacking in information
