1. Solve the problem. A company manufactures televisions in batches of 25 and there is a 1% rate of defects. Find the standard deviation for the number of defects per batch. O 0.7 O 0.9 O 0.5 O 72.8

I think The answer is 0.7

2. Find the standard deviation, a, for the binomial distribution which has the stated values of n and p. Round your answer to the nearest hundredth. n = 21; p = 0.2 Og=1.83 O g= 5.95 Og=-0.58 O g= 5.10

I think the answer is g=5.10

3. Use the given values of n and p to find the minimum usual value u - 26 and the maximum usual value u + 2. Round your answer to the nearest hundredth unless otherwise noted. 7 = 1056, p = 0.80

O Minimum: 870.8; maximum: 818.8 O Minimum: 831.8; maximum: 857.8 O Minimum: 826.42; maximum: 863.18 O Minimum: 818.8; maximum: 870.8

I think the answer is Minimum: 826.42; maximum: 863.18

4. Find the mean, u, for the binomial distribution which has the stated values of n and p. Round answer to the nearest tenth. n= 523; p = 0.7 O u=367.4 O u=364.6 O u=366.1 O u=367.8

I think the answer is u=364.6

5. A fair coin is flipped multiple times until it lands on heads. If the probability of landing on heads is 50%, what is the probability of furst landing on heads on the fourth attempt? 00.625 00.0625 00.500 O 0.382

I think the answer is 0.382
