Question

The heights of 50 students, measured to the nearest centimeters, have been found to be as follows: $161150154165168161154162150151162164171165158154156172160170153159161170162165166168165164154152153156158162160161173166161159162167168159158153154159$Represent the data given above by a grouped frequency distribution table, taking the class intervals as $160-165,165-170$, etc.

Answer 1

The data is represented in the grouped frequency distribution is tabulated below

Height (in cm)	No. of Students (Frequency)
$150-155$	$12$
$155-160$	$9$
$160-165$	$14$
$165-170$	$10$
$170-175$	$5$
Total	$50$

Hence, From the given data and above table we observe that $35$students, i.e. more than$50\%$of the total students, are shorter than $165cm.$
