Problem Solving: Show your solution. 1. The average monthly salary of the 200 workers of a construction site is Php 9800.00 with a standard deviation of Php300. If you are going to make a research with 5% margin of error, how many samples must be included in your study? Using the computed sample size, solve the mean, variance, and standard deviation of the sampling distribution. 2. The following are the scores of 4 students: (8, 6, 9, 5). If sample size 2 is drawn from this population, construct the sampling distribution table, and calculate the following: a. Mean of the sampling distribution of sample means. b. Variance of the sampling distribution of sample means. c. Standard deviation of the sampling distribution of sample means.

Compare the population variance to the mean of the sample variances. Choose the correct answer below.     A. The population variance is equal to the square root of the mean of the sample variances.   B. The population variance is equal to the mean of the sample variances.   C. The population variance is equal to the square of the mean of the sample variances.

If the mean height of bonsai trees is 52 cm with a standard deviation of 10 cm, what percent of the trees are above 82 cm? Select one: a. 0.3% O b. 82 O c. 3% O d. 0.15% Students at Roseville High School took an IQ test with a mean of 100 and a standard deviation of 15. Approximately, what percent of the students scored above 100? Answer: o represents the

Find the estimated standard error for the sample mean for n = 13 and SS = 3639. Nearest hundredths place.

1. Measure your height and find how many standard deviations you are from 50th percentile using the Anthropometry table in slide 17 in the Anthropometry slides. My height is 5 feet 7 inches. 2. Using this measured stature, estimate the lengths of your forearm, foot, and hand (https://exrx.net/Kinesiology/Segments). 3. Measure your forearm, foot, and hand using a tape measure (or some other device).( forearm= 7inches; foot=10inches; hand=22inches). 4. Indicate the error in %s for each segment (compare measured vs table value), and indicate which if your 3 segments was the furthest off.

Ms. Lorraine Finch, a fifth grade teacher has a large class of 50 students for the 2018 - 2019 school year. After giving a reading comprehension test, Ms. Finch decided to do a brief statistical analysis. A frequency distribution of the results is presented below. a. Fill in the missing pa rts of Ms. Finch’s frequency distribution. Do any necessary scrap work in the space next to the table. b. Construct a histogram of the frequency distribution.   c Is the distribution of test scores normal?

Erin is married to Glen Mills. Erin earns an income of 500. Glen earns 400. Glen and Erin live with their two dependent children who earn no income. Vaughan lives alone and earns an income of 100. 1. Statistics Canada would report the variance in income for this population is equal to? 2. Statistics Canada would report the range of incomes for this population is equal to?
