Michael wants to take French or Spanish, or both. But classes are closed, and he must apply and get accepted to be allowed to en
Brums [2.3K]

Answer:

80%.

Step-by-step explanation:

Given the following probabilities:

  • P(Micheal Being admitted to French), P(F)=50%
  • P(Micheal Being admitted to Spanish), P(S)=50%

In Probability Theory, when we have BOTH , we mean the intersection of the probabilities. Therefore:

  • P(Micheal Being admitted to BOTH French and Spanish), P(F \cap S)=20\%

We want to determine the probability that he will be enrolled in either French or Spanish (or possibly both).

Probability of either A OR B =P(F \cup S)

From Probability Theory:

P(F \cup S) = P(F)+P(S)-P(F \cap S)\\P(F \cup S) =50+50-20\\P(F \cup S) =80

The probability that he will be enrolled in either French or Spanish (or possibly both) is 80%.

A researcher wants to use a confidence interval to estimate the proportion of college students in his state who plan to vote in
Harrizon [31]

Answer:

99% confidence interval will be wider because as the level of confidence increase the width increases as well and the standard error decreases

Step-by-step explanation:

The  confidence interval is directly proportional to the sample size  hence the 99% confidence interval will be wider than the 95% confidence interval of the sample of 120 college students

using a 99% confidence interval gives a more accurate result than a 95% confidence because the standard error decreases with increase in confidence interval
