A company is going to launch an exclusive high-end smartphone. They rely on a bold marketing strategy that offers a lifetime warranty for replacing the first failure caused by normal use in each smartphone sold. The engineering team does a precise accelerated aging test on 127 smartphones and detects that 5 fail. The test is precise in simulating the real conditions of a lifetime of use. A 0.0394 probability of failure is just within the longrun budget for the marketing campaign and everyone in the company is in good spirits, until someone in the analytics department warns them that the probability of failure for each smartphone could be much higher. For example, if the true probability of failure was 0.0472 the budget would be greatly exceeded (by 20\% !) and the company would have to close. What is the probability of having observed the results of the aging test, or even better results (less failures), if the true probability of failure is 0.0472 Please use the normal approximation and introduce the answer to 3 decimal places.
The probability of observing the results of the aging test, or even better results (less failures), if the true probability of failure is 0.0472, is approximately 0.463.
What is the probability of observing the results of the aging test or better with a higher true probability of failure?To calculate the probability, we can use the normal approximation. First, we need to find the mean and standard deviation of the distribution.
The mean (μ) is equal to the number of smartphones tested multiplied by the true probability of failure, which is 127 * 0.0472 = 5.9904. The standard deviation (σ) is the square root of the product of the number of smartphones tested, the true probability of failure, and 1 minus the true probability of failure, which is sqrt(127 * 0.0472 * (1 - 0.0472)) = 2.5038.
Next, we can calculate the z-score for the observed number of failures (5) using the formula z = (x - μ) / σ, where x is the observed number of failures. In this case, the z-score is (5 - 5.9904) / 2.5038 = -0.3966.
Using the z-score, we can find the probability using a standard normal distribution table or calculator. The probability of observing the results of the aging test or better is P(z ≤ -0.3966), which is approximately 0.463.

A. java.util.Arrays(scores)
B. java.util.Arrays.sorts(scores)
C. java.util.Arrays.sort(scores)
D. Njava.util.Arrays.sortArray(scores)
The correct method to sort an array of type double[] using the java.util.Arrays class is C. java.util.Arrays.sort(scores). In Java, the java.util.Arrays class provides a set of utility methods for working with arrays, including sorting. The sort() method of the Arrays class is specifically designed to sort arrays in ascending order.
To sort an array of type double[], you would pass the array as an argument to the sort() method. In this case, the array variable is "scores". The method call would be java.util.Arrays.sort(scores).
The sort() method uses a variation of the quicksort algorithm to efficiently sort the array. It rearranges the elements of the array in ascending order based on their natural ordering or using a custom comparator.
By calling java.util.Arrays.sort(scores), the elements in the "scores" array will be rearranged in ascending order. After the sorting operation, the array will contain the same elements but in a sorted sequence.
Using the correct method is important to ensure that the sorting operation is performed correctly. The options A, B, and D are not valid methods in the java.util.Arrays class for sorting arrays of type double[]. Therefore, the correct answer is C. java.util.Arrays.sort(scores).
