Given that a box contains recipes from five categories.
The following table shows the possible categories and the associated probability for a recipe randomly chosen.
Genre Probability
Main Dish 0.421
Appetizer 0.210
Desert 0.103
Salad 0.173
Vegetable 0.093
This is a proper probability distribution function because total prob =1 and also each prob lies between 0 and 1.
The probability of randomly selecting anything but a vegetable or a main dish category
= Prob of selecting appetizer or dessert or salad

Answer:
Women has better study habit than men.
Step-by-step explanation:
For knowing who has better study habits and attitudes toward learning we have to find the mean of both the women and men data.
The first step is that we only take first 18 values of both women(X) and men(Y) data, to make them of same length
Mean is used to measure the central tendency of data which represents the whole data in the best way. It can be found as the ratio of the sum of all the observations to the total number of observations.
Calculating all values:
= 141.0556
= 121.25
Thus, women has better study habit than men. Since Mean of X is larger than Mean of Y.
