Answer:
Men can be concluded to enjoy shopping electronic activity more than women, but in weekend days. The case might not hold true for week working days also.
Step-by-step explanation:
To study : whether the percent of men who enjoy shopping for electronic equipment is higher than the percent of women who enjoy that.
- Out of 67 men, 24 said they enjoyed the activity
So, % of men enjoying the activity = (24 / 67) x 100
= 35.82%
Out of 24 women, 8 said that they enjoyed the activity
So, % of women enjoying the activity = (8 / 24) x 100
= 33.33%
