1. Given that Pr[A] = 0.35, Pr[B] = 0.64, and Pr[ A n B] = 0.23 a. Draw the Venn diagram. Then find the probabilities on the right: b. Find Pr[A|B] c. Find Pr[B|A] d. Find Pr[A U B]' e. Find Pr[A'|B]

Is this Algebra or Pre- Algebra?

Step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

it is 570
