Answer:
A is the answer because they are the data that are sourced from someplace that has originally collected it. This means that this kind of data has already been collected by some researchers or investigators in the past and is available either in published or unpublished form. This information is impure as statistical operations may have been performed on them already.

Answer:
Difference between in price of a car due to increase in VAT is $375.
Step-by-step explanation:
Since e have given that
Price of car = $15000
Rate of VAT = 17.5%
So, Amount of tax becomes
So, Total Price he has to pay is given by
but According to question,
Rate of VAT = 20%
So, Amount of tax becomes
So, Total price he has to pay is given by
Difference between both the price due to increase in VAT is given by
Hence, difference between in price of a car due to increase in VAT is $375.
Answer:
Step-by-step explanation:
Assuming a normal distribution for the amount spent by Canadian households for high-speed broadband access, the formula for normal distribution is expressed as
z = (x - u)/s
Where
x = amount spent by the Canadian households.
u = mean amount spent monthly.
s = standard deviation
From the information given,
u = $80.63 CDN
s = $27.32 CDN
We want to find the probability that the average amount will exceed $85. It is expressed as
P(x greater than 85) = 1 - P(x lesser than or equal to 85)
For x = 85
z = (85 - 80)/27.32 = 0.18
Looking at the normal distribution table, the corresponding z score is 0.57142
P(x greater than 85) = 1 - 0.57142 = 0.43
