Assuming that manager A's availability is independent of manager B's
availability, which day should Emma choose to maximize the probability that
both managers will be available?
A. Wednesday. The probability that both managers will be available is
0.93
B. Monday. The probability that both managers will be available is
0.91.
O c. Wednesday. The probability that both managers will be available is
0.66
D. Monday. The probability that both managers will be available is
0.7.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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 a secret for it not to be compromised sorry
