Considering the following scenario, which method would be most appropriate when calculating the margin of error for the population mean?

A research scholar wants to know how many times per hour a certain strand of germ reproduces. He obtains information from 47 strands of this particular germ and finds the mean to be 7.8 with a population standard deviation known to be 2.3. The population is assumed to be uniformly distributed.

A. Normal z-distribution
B. Student's t-distribution
C. More advanced statistical techniques

Because of the fact that

there is no information about population standard deviation, we cannot use normal z-distribution, we have to use students t-distribution using sample standard deviation as an unbiased estimator of population standard deviation.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
