I 1 . Find p and q given X and n. a. X - 28; n = 100 b. X = 45; 1 = 240 C. X = 120; n = 1000 d. X = 234; n = 1500 e. X = 318; n = 2300 2. Estimate the population proportions for each of the following data: a. In a plant box consisting of 120 seedlings, 80 seedlings were treated with growth enhancer. Estimate p and q. b. In a survey of 80 children, 48 like to watch horror films. Find p and q, where p is the proportion of children who like to watch horror films. 3. In a political rally, an opinion poll was conducted among the present voters if they approve the platform of the candidate. 201 said they do approve. If there were 500 individuals in the sample, what is p? What is q? A certain barangay embarked on a QUIT SMOKING program among the constituents. A survey was made among a sample of 200 smoking individuals of the village asking who would join the program. 118 said they would join the program. What are the values of p and q? 5.

For a particular school year, the Registrar of a University wanted to know the proportion of students who are enrolled in the Sciences. The enrolment data showed a total enrolment of 6534 students. Of this total, there were 4286 enrolled in various Science courses. What do the numbers say about the course preferences II of the students? Exercises 1. Listen to a mass media report on the result of a population survey. 2. Note the parameter of concern. 3. Write what you think about the report. 4. What course of action would you make arising from this informat tion, why? III 1. Find the proportions p and & for each of the following: a. X - 135, # = 378 b. X - 234, n - 512 C. X = 256, n = 624 d. X = 314, # = 850 e. X - 450, n = 1260 2. Why is p regarded as an unbiased estimator of p? 3. Describe the sample distribution of p based on large samples of size n. 4. Compute the population proportion interval estimate given n, p, and the confidence level. a. " = 300, p = 0.40, 95% confidence b. " = 500, p = 0.23, 95% confidence C. #1 = 420, p = 0.61, 90% confidence d. " = 670, p = 0.54 , 99% confidence e. " = 710, p = 0.63 , 99% confidence 5.
