Asample of 28 elements is selected to estimate a 95% confidence interval for the variance of the population. the chi-square values to be used for this interval estimation are
a. 16.151 and 40.113.
b. 14.573 and 43.195.
c. 15.308 and 44.461.
d. 11.808 and 49.645.

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.
