if the accepteable range is between .745 in and .755 in, what percentage of your sample blocks would be considered unaccesptable?
o...ok thanks
Wouldn't it depend on the mean of the sample, and the variation?
To determine the percentage of sample blocks that are considered unacceptable, you need to find the proportion of blocks that fall outside the acceptable range.
First, you need to understand what is considered acceptable. The acceptable range is between 0.745 inches and 0.755 inches.
To calculate the percentage of sample blocks that are considered unacceptable, we need to determine the number of blocks that fall outside this range.
Let's assume you have a sample size of n blocks, and you measure the thickness of each block. You need to count the number of blocks whose thickness is either less than 0.745 inches or greater than 0.755 inches.
Once you have the count of unacceptable blocks, you can divide it by the total sample size, n, and multiply by 100 to get the percentage. Here's the formula:
Percentage of unacceptable blocks = (Number of unacceptable blocks / Sample size) * 100
Remember, this calculation assumes a uniform distribution of measurements within the sample and that each block has an equal chance of falling outside the acceptable range.
So, to get the answer, you need the total number of blocks in the sample and count how many blocks have a thickness outside the acceptable range. Then, divide the count by the total number of blocks and multiply by 100 to get the percentage of unacceptable blocks.
