A fuel pump at a gasoline station doesn't always dispense the exact amount displayed on the meter. When the meter reads 1.000\text{ L}1.000 L1, point, 000, start text, space, L, end text, the amount of fuel a certain pump dispenses is normally distributed with a mean of 1\text{ L}1 L1, start text, space, L, end text and standard deviation of 0.05\text{ L}0.05 L0, point, 05, start text, space, L, end text. Let XXX represent the amount dispensed in a random trial when the meter reads 1.000\text{ L}1.000 L1, point, 000, start text, space, L, end text. Find P(0.9

y -5 = (-1/4)(x + 8)

step-by-step explanation:

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;
