Question

(d) Find and interpret the probability that a randomly selected fertilized egg hatches between 13 and 15 days. The probability that a randomly selected fertilized egg hatches between 13 and 15 days is . (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box to complete your choice. (Round to the nearest integer as needed.) A. If 100 fertilized eggs were randomly selected, exactly would be expected to hatch on day 13 or on day 15. B. If 100 fertilized eggs were randomly selected, of them would be expected to hatch between 13 and 15 days. C. In every group of 100 fertilized eggs, eggs would be expected to hatch between 13 and 15 days. (e) Would it be unusual for an egg to hatch in less than 9 days? Why? The probability of an egg hatching in less than 9 days is , so it be unusual, since the probability is than 0.05. (Round to four decimal places as needed.)

Step 1

Given: Mean (μ) = 17 days Standard Deviation (σ) = 2 days Lower Boundary = 13 days Upper Boundary = 15 days Using the normal distribution formula: \[ P(13 < X < 15) = P(X < 15) - P(X < 13) \] Calculate the z-scores for 13 and 15: \[ z_{13} = \frac{13 - 17}{2} = Show more…

00:01 There is given an normal distribution in this question.

00:03 So at the beginning of the question, there is given the mean value.

00:07 So the mean is 17 days, the mean, which is denoted by me.

00:11 This is 17 days.

00:13 And the standard division, denoted by sigma, which is two days.

00:20 Great.

00:21 And the next one.

00:22 So we have to find the values here.

00:25 So first of all, we have to find the area, which is between 13 and 15 days.

00:30 So this is the part d because the question is being started with the part d.

00:35 And i'm going to define the random variable x.

00:37 This is normally the derivative, 17 and 2.

00:39 So the probability of getting 13 and 15.

00:45 So i'm going to use the normal cdf function here.

00:48 The lower boundary is 13.

00:50 The upper boundary is 15.

00:51 And the mean is 17 and the standard division, which is 2.

00:56 Let's get the probability here.

01:00 Second and the variance.

01:02 The second option.

01:03 Going to select this is 13 comma and 15 comma this is 17 comma and 2 so the probability here which is 0 .13 and then 59 this is the probability we have for this question so 100 fertilized eggs exactly would be so in order to get the number of this one so the number of x which is equal to the probability of this interval and multiply by the number of egg.

01:39 So this is equal to 0 .13 .59 and multiply this by 100 because there are 100 x...
