Answer:
a) The probability that a hobbit picked at random is no more than 36.7 in tall is P= 0.56631.
b) The probability that a random sample of 16 hobbits have a mean height of no more than 36.7 in tall is P=0.74857.
c) The probability that a random sample of 100 hobbits have a mean height of no more than 36.7 in tall is P=0.95254.
Step-by-step explanation:
We have this parameters for the population: normally distributed with mean 36 in. and standard deviation 4.2 in.
a) The probability can be computed calculating z and looking up in a table.
The probability that a hobbit picked at random is no more than 36.7 in tall is P= 0.56631.
b) In this case, the sample standard deviation change to
.
We can calculate z with the sample standard deviation
The probability that a random sample of 16 hobbits have a mean height of no more than 36.7 in tall is P=0.74857.
c) We apply the same principle as in pont b.
We can calculate z with the sample standard deviation
The probability that a random sample of 100 hobbits have a mean height of no more than 36.7 in tall is P=0.95254.
Answer:
50.31 yards
Step-by-step explanation:
divide the length value by 914.4
46,000/914.4 = 50.31
Mark brainliest please!
They spent 754% of their budget on props because $1300-$754=546 and that’s how much they ended up with so $754 is the answer! I hope I’m right and I hope this helped
