Answer:
1. 50%
2.
Step-by-step explanation:
1. The way to approach the probability of rolling an odd number is to start with the total numbers. Therefore, each dice has three even sides and three odd sides. Mathematically - 50% chance of landing on the odd number.
2. You have 'P' which represents probability. "N" which is the given ratio of the number of outcome. (NP) total number of the possible outcome.
P = N / NP
Dice has 6 faces. I.E. 1,2,3,4,5,6
= 6
NP, therefore, is the total number of possible outcome.
Faces less than 6. (1,2,4, and 5)
N = 5
P = N / NP = ; it can't be reduced.

Step-by-step explanation:
<u>Part A</u>
Assuming that conditions have been met for the interval, we use the formula where
represents the sample mean,
represents the critical value,
represents the sample standard deviation, and
is the sample size.
The critical value of for an 80% confidence level with degrees of freedom
is equivalent to
Thus, we can compute the confidence interval:
Therefore, we are 80% confident that the true mean age of all customers is between 30.17 and 35.11 years.
<u>Part B</u>
The margin of error is
