How many significant digits is in 70.00?

all below

Step-by-step explanation:

Part A: The hypothesized value of proportion is P=0.92. So for sample size n=200, the standard deviation of distribution is σ=sqrt/px(1-p) divided by n = 0.0192

For given observation, the sample proportion p= 175/200 = 0.875

So the test statistic is Z= p-P/σ = 0.875 - .92/ 0.0192 = -2.34

Required probability = P(Z< -2.34)=0.0096

Therefore, the probability that in the simple random sample of 200 orders, is as small as the proportion in the auditors' sample or smaller is just less than 1%.\

Part B: It is 99% probable that the proportion is not 0.92. There is enough evidence, at the 0.01 level, that Monogram Masters ships less than 92% of its orders on time.
