Suppose the neck size of men is normally distributed, with a mean of 15.5 inches and a standard deviation of 0.5 inch. a shirt manufacturer is going to introduce a new line of shirts. assume that if your neck size falls between two shirt sizes, you purchase the next larger shirt size. how many of each of the following sizes should be included in a batch of 2,000 shirts? (assume that if your neck size falls below 14 you will purchase a size 14 shirt. assume that if your neck size falls above 17 you will not purchase a shirt. note: the answer blanks may not add up to exactly 2,000 shirts. round your answers to the nearest whole number.)

step-by-step explanation:

range is infinite on both x and y axis positive and negative

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
