In a random sample of 250 toner cartridges, the mean number of pages a toner cartridge can print is 4302 and the standard deviation is 340. 4 (a) suppose a histogram of the data indicates that the sample data follow a bell-shaped distribution. according to the empirical rule, 99.7% of toner cartridges will print between (b) assuming that the distribution of the data are bell. shaped, determine the percentage of toner cartridges whose print total is between 3622 and 4982 pages (c) if the company that manufactures the toner cartridges guarantees to replace any cartridge that does not print at least 3622 pages, what percent of cartridges can the firm expect to be responsible for replacing, according to the empirical rule? and pages

a) According to the empirical rule, 99.7% of toner cartridges will print between 3282 and 5322 pages.

b) 95% of the toner cartridges have a print total between 3622 and 4982 pages.

c) The firm can expect to be responsible for replacing 5% of cartridges.

Step-by-step explanation:

The mean number of pages a toner cartridge can print is 4302 and the standard deviation is 340, so

(a) Suppose a histogram of the data indicates that the sample data follow a bell-shaped distribution. According to the Empirical Rule, 99.7% of toner cartridges will print between

The Empirical Rule states that 99.7% of the values of X of a set with mean and standard deviation belong to the following interval

We have that .

So

According to the empirical rule, 99.7% of toner cartridges will print between 3282 and 5322 pages.

(b) Assuming that the distribution of the data are bell. shaped, determine the percentage of toner cartridges whose print total is between 3622 and 4982 pages

How many standard deviations are those values from the mean?

3622 pages is 2 standard deviations below the mean.

--------------

4982 pages is 2 standard deviations below the mean.

The Empirical Rule states that 95% of the values of X of a set with mean and standard deviation belong to the following interval

So, 95% of the toner cartridges have a print total between 3622 and 4982 pages.

(c) If the company that manufactures the toner cartridges guarantees to replace any cartridge that does not print at least 3622 pages, what percent of cartridges can the firm expect to be responsible for replacing, according to the Empirical Rule?

In b), we found that 3622 pages is 2 standard deviations below the mean.

The empirical rule states that 5% of the values are expected to be 2 standard deviations below the mean.

So, the firm can expect to be responsible for replacing 5% of cartridges.

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
