Question

identify the lower class limits, upper class limits, class width, class midpoints, and class boundaries for the given frequency distribution. also identify the number of individuals included in the summary. blood platelet count of males (1000 cells/μl) frequency 0 - 99 1 100 - 199 47 200 - 299 83 300 - 399 19 400 - 499 0 500 - 599 1 600 - 699 0 identify the upper class limits (in 1000 cells/μl). 99, 199, 299, 399, 499, 599, 699 (type integers or decimals. do not round. use ascending order.) identify the class width (in 1000 cells/μl). 100 (type an integer or a decimal. do not round.) identify the class midpoints (in 1000 cells/μl). 49.5, 149.5, 249.5, 349.5, 449.5, 549.5, 649.5 (type integers or decimals. do not round. use ascending order.) identify the class boundaries (in 1000 cells/μl). - 0.5, 99.5, 199.5, 299.5, 399.5, 499.5, 599.5, 699.5 (type integers or decimals. do not round. use ascending order.) identify the number of individuals included in the summary. (type an integer or a decimal. do not round.)

Explanation:

Step1: Sum up frequencies

Add all the frequencies in the frequency - distribution table. The frequencies are 1, 47, 83, 19, 0, 1, 0.
$1 + 47+83 + 19+0 + 1+0$

Step2: Calculate the sum

$1+47 = 48$, $48+83 = 131$, $131+19 = 150$, $150 + 0=150$, $150+1 = 151$, $151+0 = 151$.
$1+47+83 + 19+0 + 1+0=151$

Answer:

151
