In this question we can see that it is actually the addition of fractional numbers. The addition should be done carefully. Now let us get down to the addition part.
Total number of books i had = (1/8) + (1/5)
= (5 + 8)/40
= 13/40
So the total number of books that i had was 13/40. I hope this is the answer you were looking for. Although the result seems a bit awkward, but still this is the correct result. Hopefully the procedure is clear enough for you understand. In future you can always use this procedure for solving similar type of problems.

1/8+ 1/5
= 5/40+ 8/40
= 13/40

The final answer is 13/40 books~

A courier service company wishes to estimate the proportion of people in various states that will use its services. Suppose the

kolbaska11 [484]

The probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.

The true proportion (p) is given to be 0.03.

Therefore, Mean (μ) = p = 0.03.

The standard error of sampling distribution can be calculated using the formula σ = √[{p(1 - p)}/n], where n, is the sample size, that is, n = 476.

Therefore, σ = √[{0.03(1 - 0. 03)}/476] = 0.00782.

Since, np = 14.28 and n(1 - p) = 461.72 are both greater than 5, we assume the sample is normally distributed.

Since, we are asked to find the probability that the sample proportion is less than 0.04, we using our calculator, enter as following:

Normalcdf(-100000000,0.04,0.03,0.00782), which gives us the value 0.8995 or 89.95%.

Thus, the probability that the sample proportion will be less than 0.04 is 0.8995 or 89.95%.
