Question

identify the lower class limits, upper class limits, class width, class midpoints, and class boundaries given frequency distribution. also identify the number of individuals included in the summary. blood platelet count of females (1000 cells/μl) frequency 100 - 199 25 200 - 299 91 300 - 399 26 400 - 499 1 500 - 599 3 (type integers or decimals. do not round. use ascending order.) identify the upper class limits. 199, 299, 399, 499, 599 (type integers or decimals. do not round. use ascending order.) identify the class width. 100 (type an integer or a decimal. do not round.) identify the class midpoints. 149.5, 249.5, 349.5, 449.5, 549.5 (type integers or decimals. do not round. use ascending order.) identify the class boundaries. 99.5, 199.5, 299.5, 399.5, 499.5, 599.5 (type integers or decimals. do not round. use ascending order.) identify the number of individuals included in the summary. (type a whole number.)

Explanation:

Step1: Sum the frequencies

To find the number of individuals, sum all frequencies.
$25 + 91+26 + 1+3$

Step2: Calculate the sum

$25+91 = 116$, $116+26=142$, $142 + 1=143$, $143+3 = 146$

Answer:

$146$
