Answer 1

Answer:

Sunny equals 170

Cloudy equals 120

Rainy equals 55

Snowy equals 20

Explanation:

Weather - - - - On-time - - - Delayed----- Total

Sunny----------- 167 - - - - - - - - 3------------- 170

Cloudy - - - - - -115 - - - - - - - - 5 - - - - - - - 120

Rainy - - - - - - 40 - - - - - - - - 15 - - - - - - - 55

Total - - - - - - 330 - - - - - - - 35 - - - - - - - 365

Therefore, marginal distribution of weather condition in counts :

Sunny : 170

Cloudy : 120

Rainy : 55

Snowy : 20

Answer 2

Answer:

Sunny: 47%

Cloudy : 33%

Rainy : 15%

Snowy : 5%

Explanation:

The marginal distribution of weather condition in percentages shows what percent of the total days were sunny. To do this, divide the number of days by the total days in a year (365).

For example, snowy.

20/365 = 5%
