The length and width of panels used for interior doors (in inches) are denoted as and , respectively. Suppose that and are independent, continuous uniform random variables for and , respectively. (a) By integrating the joint probability density function over the appropriate region, determine the probability that the area of a panel exceeds 91 square inches. Round your answer to three decimal places (e. g. 98.765). Enter your answer in accordance to the item a) of the question statement 0.388

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

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;

probably .5

i can on others if necessary.

the answer is a beach is the best place to be
