The file P02_35.xlsx contains data from a survey of 500 randomly selected households. a. Suppose you decide to generate a systematic random sample of size 25 from this population of data. How many such samples are there? What is the mean of Debt for each of the first three such samples, using the data in the order given? b. If you wanted to estimate the (supposedly unknown) population mean of Debt from a systematic random sample as in part a, why might it be a good idea to sort first on Debt? If you do so, what is the mean of Debt for each of the first three such samples? Please provide answer in Excel format with steps how to do it. I am not able to upload full table.

how many 4 digit numbers divisible by 5 can be formed from 0,1,3,5,7,9 if repetition is not allowed and 0 and 1 Can not be next to each other.

i can do the first part. there are 2 cases

case 1, the number ends in zero.
5 x 4 x 3 x 1. but i dont know how to account for the zero and one not being able to be next to each other. i counted 12 possible numbers that would end in 10.

case 2, the number ends in 5. (and cant start with 0)
5 x 4 x 3 again i dont know how to account for all the possible cases where 1 and 0 are next to each other.
