I only need to know what do you think the null and altenative hypothesis is!

The story:
A plant breeder claims that a new variety of fruit bush he has produced gives a higher yield of fruit than the variety it will replace. A random sample of 10 bushes of the new variety is grown and the yields of the bushes recorded. The old variety has an average yeild of 5.2kg/bush. It is assummed that the yield from each bush is an independent observation from a normal distribution. Test at 5% level of significance, the breeder's claim.

I felt that
(null hypothesis) H0: mean=5.2
(alternative hypothesis) H1: mean<5.2

but my teacher said that it shoulde be:
(null hypothesis) H0: mean=5.2
(alternative hypothesis) H1: mean>5.2

Side question: How big is the range of the p-value(observed significance value)?

F(x) = 8/x.
F-1(x) = x/8???

Is that correct and why, or does it remain as 8/x...

because, y= 8/x » x = 8/y » xy = 8 » 8/x?
