Answer #1
Day Relative frequency
Monday

53/400*100 = 13.25%

Tuesday 15.75%
Wednesday 17.75%
Thursday 14.25%
Friday 13.75%
Saturday 11.50%
Sunday 13.75%

Total number of births in the week = 53+63+71+57+55+46+55 = 400

2.1.23)

Total plane crashes during the past 70 years = 219+59+375+192+201 = 1046

Cause Relative frequency
Pilot error 219/1046*100 = 20.94%
Other human error 5.64%
Weather 35.85%
Mechanical problems 18.36%
Sabotage 19.22%


As per the Relative frequency, Weather is the most serious threat to aviation safety and nothing can be done about it.
