The birth lengths of healthy, full term newborn Who-tots are (approximately) normallt distributed with a mean of 15. cm and a standard deviation of 2.7 cm. (a) What is the probability that a randomly selected newborn Who-tot will be more than 16 cm long?
(b) What is the probability that the mean length of a simple random sample of 40 newborn Who-tots will be more than 16 cm?
(c) What is the 65th percentile for newborn Who-tot birth length?

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
