A + s = 279
s = 2a
a + 2a = 279
3a = 279
a = 279/3
a = 93 <=== adult
s = 2a
s = 2(93)
s = 186 ....students
Solution: We are given a population follows a normal distribution with Mean and standard deviation
According to central limit theorem, if we have a population with mean and standard deviation and take large samples from the population, then the distribution of samples means will be approximately normally distributed with mean and standard deviation given below:
Therefore, for the given example the distribution of sample means will be approximately normal with mean and standard deviation given below:
rounded to 2 decimal places.
The answer is d. the y intercept is 3 and the slope is 4
2 yards. 2 inches is 2 yards because 1 yard is 36 inches
