In the US, 77% of all teens have a TV in their bedrooms, while 59% of all teens in Spain have them. A simple random sample of 500 teens from the US and 300 from Spain are selected and all are asked whether they have a
TV in their bedrooms. Let 9, -be the difference in the sample proportions of teens with a TV in their bedrooms,
where
is the sample proportion of US teens with a TV in their bedrooms and is the sample proportion of
Spanish teens with a TV in their bedrooms.
What is the shape of the sampling distribution of the difference in the two sample proportions?
approximately uniform
approximately Normal
skewed to the right
skewed to the left

Name the most appropriate metric unit for each measurement like a length of an carrot

Asap! i'm not good math and i'm lost.

Our star pitcher, foster enlight, can throw a pitch so fast that it gets to the catcher’s mitt before it leaves foster’s fingers! if the team wins a game then the probability that foster was pitching is 0.8 but only if foster had at least one day’s rest since his last pitching assignment. if foster does not have a day off and the team still wins, the probability that foster was pitching drops by half of what it was on the previous day. if the team wins three games in succession from the toronto tachyons and foster pitched in game #2, what is the probability that he pitched in one or more of the other games? (assume that foster did not pitch on the day before the first game of this three game series.)
