Drug sniffing dogs must be 95% accurate in their responses because their handlers don't want them to miss durgs and also don't want false positives. a new dog is being tested and is right in 46 of 50 trials. find the 95% confidence interval for the proportion of times the dog will be correct

95% Confidence interval:  (0.8449,0.9951)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 50

Number of times the dog is right, x = 46

95% Confidence interval:

Putting the values, we get:

(0.8449,0.9951) is the required 95% confidence interval for the proportion of times the dog will be correct.

168

step-by-step explanation:

i am pretty sure that the answer is 168

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
