The leader of the association of jeepney drivers claims that the average daily take home pay for all jeepney drivers in Baguio City is 400 pesos. A random sample of 100 jeepney drivers in Baguio City was interviewed and the average daily take home pay of these drivers is found to be 425 pesos. Use a 0.05 significance level to find out if the average daily take home pay of all jeepney drivers in Baguio City is different from 400 pesos. Assume that the population variance is 92 pesos.

Identify if the following statements are predicate logic. Give a domain of discourse for each propositional function. (3 items x 5 points)

According to one of the teachers in your school, the senior high school students sleep for 7 hours a day on a weekday. You wanted to prove this claim by making a survey of 50 senior high school students. You will be asking the students about how long they sleep in a regular weekday. Record the results of your survey. As a researcher, you need to compute the mean and standard deviation of your sample.

Create a 90%, 95%, and 99% confidence interval for the mean time of sleep for senior high school students. In your report, the raw data should be present, and the computation should be complete

If a population has a variance of 6.4, what is the variance of the sampling distribution of it's means? The sampling distribution has a sample size of 2 and all possible samples are drawn with replacement

Random samples of size N=2 are drawn from a finite population consisting of the number 5,6,7,8, and 9. Compute for the mean, Variance,and Standard deviation, and also the mean, Variance, and the Standard deviation of the sample mean
