QuestionSuppose the birth weights of full-term babies are normally distributed with mean 3250 grams and standard deviation grams. Complete parts (a) through (c) below. (4) n 17 (c) Suppose the area under the normal curve to the riaht of is 0.0228 . Provide an interpretation of this result. Select the correct choice below and fill in the answer box to complete your choice. (Type a whole number.) A. The probability is 0.0228 that the birth weight of a randomly chosen full-term baby in this population is less than grams. B. The probability is 00228 that the birth weight of a randomly chosen full-term baby in this population is more than grams. solve this View an example Get more help - Clear all Check answer
Studdy Solution
STEP 1
1. The birth weights are normally distributed with a mean () of 3250 grams and a standard deviation () of 480 grams.
2. The area under the normal curve to the right of is 0.0228.
STEP 2
1. Understand the given probability statement.
2. Interpret the probability in terms of birth weights.
STEP 3
Understand the given probability statement: The area under the normal curve to the right of is 0.0228. This means that the probability of a randomly chosen full-term baby having a birth weight greater than 4210 grams is 0.0228.
STEP 4
Interpret the probability in terms of birth weights:
Since the area to the right of 4210 is 0.0228, this corresponds to option B. The probability is 0.0228 that the birth weight of a randomly chosen full-term baby in this population is more than 4210 grams.
The correct interpretation is:
B. The probability is 0.0228 that the birth weight of a randomly chosen full-term baby in this population is more than grams.
