Watson Glaser question

[en.sald]

Hi all, would be grateful for reasoning behind the answers to the two WG questions below

1) Current accounts and savings accounts are both types of bank account, which differ in that current accounts are always no-interest bearing deposit accounts, whereas savings accounts earn interest. Another difference is that the minimum balance required to maintain a savings account is usually low, but for a current account it is much higher in comparison. Tim recently opened a current account with Delta Bank.

Tim doesn’t earn interest with his deposits in Delta Bank
Answer: This deduction is not made – why?

2) The bleep test is a running test used to estimate an athlete’s aerobic capacity. A new study proves that lower bleep test scores are strongly related to an increased risk of cardiovascular disease in adults aged over 50.

The study shows a positive correlation between bleep test score and increased risk of developing cardiovascular disease in adults aged over 50.
Answer: This inference is false - why?

For deductions, for the statement to follow, it must be explicitly true. I guess cause we don’t know if Tim has any other accounts with delta bank, we don’t know 100% that he doesn’t earn interest on any of his deposits (Not completely sure on this one)

For the inference I’m pretty sure it’s a negative correlation not positive. Here, the statement implies that as one variable (bleep test scores) decreases, the other (risk of cardiovascular disease) increases. For positive it would be that as the bleep test scores increase, the risk of cardiovascular disease also increases (or the other way, both decreasing)

Thank you, that's really clear!

Zi48 is correct for both. First one just states Tim made a new current account with Delta; however, no where does it say he didn’t already have a savings account with them. And no where does it say that you cannot have both accounts so we wouldn’t be able to confidently say that Tim isn’t earning interest. With deduction, it has to follow completely.

Yup negative correlation so would not be true
