Suppose that in a sequence of n Bernoulli trials, the probability p of success on each trial is unknown. Suppose also that p0 is a given number in the interval (0, 1), and it is desired to test the following hypotheses: H0: p = p0,
H1: p = p0.
Let Xn denote the proportion of successes in the n trials, and suppose that the given hypotheses are to be tested by using a χ2 test of goodness-of-fit.

Required:
Show that the statistic Q can be written in the form:

Q= n(Xn- po)^2/ po(1-po)

step-by-step explanation:

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

for future students the answer is b
