The ExceptionLab class provided: – Creates an array of 100
elements and fills it with random numbers from 1 to 100. – It asks
the user for an index value between 0 and 99. – Prints the element
at that position. – If a number > 99 is entered by the user, the
class will abort with an ArrayIndexOutOfBoundsException • Modify
the ExceptionLab: – Add a try-catch clause which intercepts the
ArrayIndexOutOfBounds and prints the message: Index value cannot be...

Student stress at final exam time comes partly from the
uncertainty of grades and the consequences of those grades. Can
knowledge of a midterm grade be used to predict a final exam grade?
A random sample of 200 BCOM students from recent years was taken
and their percentage grades on assignments, midterm exam, and final
exam were recorded. Let’s examine the ability of midterm and
assignment grades to predict final exam grades.
The data are shown here:

The subjects in the data are college students. In the data, id is student ID, anxiety is student’s anxiety score via Anxiety Scale, selfest is student’s self-esteem score via Rosenberg Self-esteem Scale, GPA is student’s GPA; for gender, 0=female, 1=male; for grade, 1=freshman, 2=junior, 3=senior. We have known that population mean for Anxiety Scale is μ=60 with σ=10. Raise relevant questions ( 2 questions is fine) about the data extensively, the questions can be either about descriptive analysis or inferential...

Terrance is age 71 and retired. Beginning in 2018, he must start taking minimum distributions from his IRA account that had a balance of $150,000 as of December 31, 2017, Make these three assumptions: His IRA will earn 8% per year, he will withdraw the minimum distribution on the last day of each calendar year, and only one distribution will be taken in 2018. Calculate the amount of his distribution for years 2018 through 2022 and the ending balance in...

The task involves writing a C++ program that determines the prime numbers between 1 and 100. The steps you should follow to identify the prime numbers are the following. 1. The number 1 is not a prime number, so it should be scratched. 2. Starting from the first prime number, which is 2, you scratch all the numbers that are the multiple of 2. You should not scratch out 2 itself. 3. The next number in the sequence after the...
