Since 6. 3, and 4 are all factors of 12 (with a bit of guess and check), we get 2/12 (since 6*2=12 and 1*2=2)+8/12+3/12=13/12 - A
Triangle A.
The angle is less that 90 degrees.

Step-by-step explanation:
Answer:
The probability that the sample proportion is more than 0.35 believe movie trailers reveal too much is 0.1539.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:
The information provided is:
<em>p</em> = 0.32
<em>n</em> = 250
Since the sample size is quite large, i.e. <em>n</em> = 250 > 30, the central limit theorem can be used to approximate the sampling distribution of sample proportion by a Normal distribution.
Compute the probability that the sample proportion is more than 0.35 believe movie trailers reveal too much as follows:
Thus, the probability that the sample proportion is more than 0.35 believe movie trailers reveal too much is 0.1539.
