wow 30th century archeologists still work from tents ... and there are still places to dig... and the A.D.2013 temple hasn't since been demolished to make way for an expansion of the PIE or CTE or new shopping mall...

looks like our future is still not gone case yet

Hi!

From the picture I gather that you went to countries around the Mediterranean area? Did you plan your journey yourself, or did you went with a group?

Thanks!

It's perfectly fine not to standardize the normal distribution in Q12(ii). It's just a habit of mine from questions to find unknowns from given probability value(s) - which is not really necessary here

Ok I'm back after a short hiatus!

For Q10(iv), yes you should get the same answer using the binomial distribution X ~ B (3, 0.62994) where the random variable X is the is the number of gardeners with > 75 plants that will flower. So,

P (X ≥ 2) = 1 − P (X ≤ 1) = ... using GC ... = 0.691

Q11(ii) is a little tricky in the sense that you are actually testing for whether the average length is less than 300 m i.e.

Ho : μ = 0
H1 : μ < 300

In this case, if Ho is rejected ⇒ average length of string is less than 300 m which counters the manager's claim of at least 300 m.

Instead, if we were to test for H1 : μ > 300, accepting or rejecting Ho wouldn't make any difference in both cases since μ will still be within "at least 300 m" territory.

Q9(ii) Hmmm I'm inclined to think that a "strong negative linear correlation" would suffice to cover the "age of car increases/price decreases part" for the (presumably) 1-mark comment since the other mark would go towards the calculation of value of the coefficient. But who am I to go against Cambridge if it's true to markers' report said this!
