For the following estimated slope coefficients and their heteroskedasticity robust standard errors, find the t-statistics for the null hypothesis H0: β1 = 0. Assuming that your sample has more than 100 observations, indicate whether or not you are able to reject the null hypothesis at the 10%, 5%, and 1% level of a one-sided and two-sided hypothesis. (a) 1 = 4.2, SE( 1) = 2.4
(b) 1 = 0.5, SE( 1) = 0.37
(c) 1 = 0.003, SE( 1) = 0.002
(d) 1 = 360, SE(1) = 300

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

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
