Consider a binomial experiment with n trials and r successes. to construct a test for a proportion p, what value do we use for the z value of the sample test statistic?
r/n
(r/n)2
n/r
2r/n

value we use for z value of  sample test  is r/n

Step-by-step explanation:

Given data

proportion p

trials  = n

successes = r

to find out

what value we use for z value of  sample test

solution

here

we know that

Probability of a success in single trail test = Number of successes/Number of trails

Probability of a success in single trail = r / n

so that

value we use for z value of  sample test  is r / n

44

step-by-step explanation:

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.
