Whether of not the PMCC for the population is greater than zero (h₀ rejected)

coefficient is greater than 0

test whether or not the mean length of all the strips, cut by the second machine, is greater than a (h0 not rejected)

There is insufficient evidence that the mean length of strips is

Test whether or not the PMCC for all countries is greater than zero (reject h0)

(compare r to critical) so there is evidence that the pmcc is greater than 0/there is positive correlation

carry out a suitable hypothesis test to investigate Stav’s belief [that there is a correlation between Daily Total Sunshine and Daily Maximum Relative Humidity at Heathrow
