Use the TI-84 Plus calculator to answer the following. (a) What proportion of broilers weigh between 1185 and 1283 grams? (b) What is the probability that a randomly selected broiler weighs more than 1650 grams? (c) Is it unusual for a broiler to weigh more than 1710 grams? Round the answers to at least four decimal places. Part 1 of 3 The proportion of broilers that weigh between 1185 and 1283 grams is Part 2 of 3 The probability that a randomly selected broiler weighs more than 1650 grams is Part 3 of 3 because the probability that a broiler weighs more than 1710 grams is (Choose one) V fullscreen

Step 1

Part (a):

Here, the population mean is, μ = 1,521 and the population standard deviation is, σ = 166.

The required proportion must be found between the lower bound of 1,185 and the upper bound of 1,283.

In a TI-84 Plus calculator, go to 2nd > VARS > 2.

Then enter the following:

lower: 1185

upper: 1283

μ: 1521

σ: 166.

Press Enter.

The result is 0.0543439548.

Thus, the required proportion is 0.5434.

Step 2

Part (b):

If a weight is more than 1,650 grams, it must be between 1,650 and infinity. Since infinity cannot be typed on the calculator, a very large number can be taken instead.

In a TI-84 Plus calculator, go to 2nd > VARS > 2.

Then ente...
