Hello

Please I really tried to find a solution but I am not good at maths!!! Thank you for anyone who can help me. Here are the exercises:

Electricity cost 10.36p per unit day-time or 4.67 per unit night time but to qualify for the night time rate customers need to pay an extra £10.49 a quarter (13 weeks) for a special meter.

How many units (to the nearest whole unit) on average per week would a customer need to use at night time to break even on the extra cost?

If a customer made an overall saving of £20 over the quarter how many units (to the nearest one) would he have used at the night time rate?

If a customer used a total of 125 night-time units over a quarter would this result in a loss or a saving and by how much (to the nearest p) allowing for the extra charge for the meter?

Thanks

How do you perform a G-test on the following data?

Category | Observed
A___________12
B___________6
C___________9

The formula I have for G-test is

G = 2 x [sum of]O ln (O/E)

where O is the observed and E is the expected (9)

And to get G for the data apparently you divide by a correction factor:

Correction factor: 1 + [(number of categories)² - 1]/6(number of observed frequencies)(degrees of freedom)]


But at the end I got G to be -0.206. Surely it can't be negative? The critical value for 5% significance level at 2 degrees of freedom is 5.99.
