A programmer plans to develop a new software system. In planning for the operating system that he will? use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 90?% confident that his estimate is in error by no more than four percentage points? B) Assume that a recent survey suggests that about 91?% of computers use a new operating system

A programmer plans to develop a new software system. In planning for the operating system that he will​ use, he needs to estimate the percentage of computers that use a new operating system. How many computers must be surveyed in order to be 95​% confident that his estimate is in error by no more than five percentage points question marks?

Complete parts​ (a) through​ (c) below. Round to nearest integer.

Assume that nothing is known about the percentage of computers with new operating systems.

n= ?

Assume that a recent survey suggests that about 89​% of computers use a new operating system.

Does the additional survey information from part​ (b) have much of an effect on the sample size that is​ required?

A - Yes, using the additional survey information from part​ (b) dramatically increases the sample size

B. - ​No, using the additional survey information from part​ (b) does not change the sample size.

C. - Yes, using the additional survey information from part​ (b) dramatically reduces the sample size.

D. - No, using the additional survey information from part​ (b) only slightly increases the sample size

You recently started working in at a University in the Math department as a software programmer. You need to build an app that can calculate the mod of two numbers. Users need to enter num1 and num2. The app should perform the calculation and display the output as num1 mod nub2 operation.

For example, 25 mod 5=0

24 mod 5 = 4

Once you implement the mod operations, then you need to add following buttons.

• Addition
• Subtraction
• Division
• Power

Follow these steps to complete the lab.

1. Create the android studio project
2. Use Android studio layout editor
3. Add textboxes and labels according to the UI
4. Add Button in the UI
5. Review the XML code of the design
6. Declare the variable before the oncreate function
7. Read the value from textboxes and assign it to the variable
8. Add the click event for the button
9. Display the output
10. Declare the variable before the oncreate function

Arrays provide the programmer the ability to store a group of related variables in a list that can be accessed via an index. This is often very useful as most programs perform the same series of calculations on every element in the array. To create an array of 10 integers (with predefined values) the following code segment can be utilised:

int valueList[10] = {4,7,1,36,23,67,61,887,12,53};

To step through the array the index '[n]' need to be updated. One method of stepping through the array is via a 'for' loop. Based on the array ‘valueList’ create a small C++ application utilising a 'for' loop that steps through the array and determines the largest number in the list and prints out the index and value. Hint: Consider creating an integer that stores the current largest integer and then compares it with the next indexed value.
