Alocal company makes a candy that is supposed to weigh 1.00 ounces. a random sample of 25 pieces of candy produces a mean of 0.996 ounces with a standard deviation of 0.004 ounces. construct a 98 percent confidence interval for the mean weight of all such candy. assume that x, the weight of a candy, is distributed normally.

(0.994, 0.998)

Step-by-step explanation:

Given : Sample size : n= 25 < 30 , so we use t-test.

Critical t-value use for 98% confidence :

Formula to find the confidence interval :-

i.e.

Hence, the required confidence interval : (0.994, 0.998)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:
