The RC and More Superstore decides to track customer complaints as part of their ongoing customer satisfaction improvement program. After collecting data for two months, their check sheet appears as follows:

Type of Problem Frequency

$($number of times$)$

Batteries not included $5$

Items damaged when received $5$

Literature not included in box $8$

Parts missing $24$

Unit not working $3$

If they construct a Pareto chart, how many of these categories are required to make up $53\%$ of all complaints?
