**Estimating Sample Size for Software Testing: An Educational Perspective**A programmer is planning to develop a new software system. To ensure its compatibility, he must estimate the percentage of computers using a new operating system. The goal is to be 95% confident that the estimate is accurate within a margin of error of two percentage points. Examine the following tasks to calculate the necessary sample size.### Tasks:a) **Initial Estimation Without Prior Data**- **Objective:** Determine the sample size required without prior knowledge of the percentage of computers using the new operating system.- **Formula:** Not provided, but would typically involve using statistical formulas for sample size estimation.- **Note:** Round up to the nearest integer.b) **Estimation Based on Survey Data**- **Objective:** Use recent survey data suggesting 96% of computers are using a new operating system to estimate the sample size.- **Note:** Round up to the nearest integer.c) **Impact of Survey Information on Sample Size**- **Analysis:** Assess whether the survey data from part (b) affects the required sample size. - **Options:** - **A.** No, using the survey does not change the sample size. - **B.** Yes, it dramatically increases the sample size. - **C.** Yes, it dramatically reduces the sample size.### Conclusion:Click to select the appropriate answer in part (c) to understand how previous survey data can impact the estimation process for sample sizes.This exercise emphasizes the importance of statistical techniques in software testing and compatibility analysis. Proper sample size estimation is critical in drawing reliable conclusions from survey data.

How many computers must be surveyed in order to be 95% confident that his estimate is in error by no more than two percentage points? Complete parts (a) through (c) below. a) Assume that nothing is known about the percentage of computers with new operating systerms. n= (Round up to the nearest integer.) b) Assume that a recent survey suggests that about 96% of computers use a new operating system. n= (Round up to the nearest integer.) c) Does the additional survey information from part (b) have much of an effect on the sample size that is required? O A. No, using the additional survey information from part (b) does not change the sample size. O B. Yes, using the additional survey information from part (b) dramatically increases the sample size. OC. Yes, using the additional survey information from part (b) dramatically reduces the sample size. Click to select your answer(s).

Using the data in GPA2 on 4,137 college students, the following equation was estimated by OLS: colgpa = 1.392 – .0135 hsperc + .00148 sat n = 4,137, R = .273, where colgpa is measured on a four-point scale, hsperc is the percentile in the high school graduating class (defined so that, for example, hsperc = 5 means the top 5% of the class), and sat is the combined math and verbal scores on the student achievement test. (i) Why does it make sense for the coefficient on hsperc to be negative? (ii) What is the predicted college GPA when hsperc = 20 and sat = 1,050? (iii) Suppose that two high school graduates, A and B, graduated in the same percentile from high school, but Student A's SAT score was 140 points higher (about one standard deviation in the sam- ple). What is the predicted difference in college GPA for these two students? Is the difference large? (iv) Holding hsperc fixed, what difference in SAT scores leads to a predicted colgpa difference of .50, or one-half of a grade point?…
