A research scholar wants to know how many times per hour a certain strand of virus reproduces. He wants to construct the 98%98% confidence interval with a maximum error of 0.180.18 reproductions per hour. Assuming that the mean is 1212 reproductions and the variance is known to be 4.414.41, what is the minimum sample size required for the estimate? Round your answer up to the next integer.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

definitely a. the others have almost all data points on one side of the line.
