The food marketing institute shows that 17% of households spend more than $100 per week on groceries. assume the population proportion is p = .17 and a sample of 800 households will be selected from the population. use z-table. calculate ( ), the standard error of the proportion of households spending more than $100 per week on groceries (to 4 decimals). what is the probability that the sample proportion will be within +/- .02 of the population proportion (to 4 decimals)? what is the probability that the sample proportion will be within +/- .02 of the population proportion for a sample of 1600 households (to 4 decimals)?

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
