Answer:

Liam has finished 30 of his lessons

Jenny has completed 15 out of 20 lessons, which means that she has completed 75% of her lessons. If Liam has completed the same percentage of lessons, then he has completed 30 of his lessons. 40(.75) = 30.

Step 2;  1st Sample for comparison by John are random lonely people  and Second Sample are random non lonely people. so the two samples are independent on each other and will give different  measurement based on quality of sleep.   So the design does not use a related sample

butalik [34]
It's moderate positive because when the number is closer to zero the weaker it is and the closer to one its stronger so since 0.44 is in more in the middle it moderate and since there is no negative sign which is - then it moderate positive. Btw I took the test and it was right.
