Step-by-step explanation:
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:
The t-value is 2.0049.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 55 - 1 = 54
Now, we have to find a value of T, which is found looking at the t table, with 54 degrees of freedom(y-axis) and a confidence level of 0.95(). So we have T = 2.0049
The t-value is 2.0049.
