1.if the population of ABM students of malaya integrated High School has a mean of 12.45, what is the mean of the sampling distribution of its mean?

The mean response time on a task for 10 younger children (6-10 y.o.a.) is 45 and the mean response time for 14 older children (11-16 y.o.a.) is 30. What is the weighted mean for the two groups (round to nearest tenth)? -> SHOW YOUR WORK ON YOUR SCRAP PAPER!!!        36.25     37.5     38.75     answer not listed- see work on scrap paper

1. Suppose the proportion of American adults who work at home is 40%. For a random sample of 100 American adults, what is the distribution of the sample proportion?

A random sample of 25 Berkeley College students was asked, “How many hours per week typically do you work outside the home?” Their responses were as follows: {0, 0, 15, 20, 30, 40, 30, 20, 35, 35, 28, 15, 20, 25, 25, 30, 5, 10, 30, 24, 28, 30, 35, 15, 15} a. Find the mean, the median and the mode of hours worked outside the home for the sample data. Show all your work to justify your answer. b. Use the above data to complete the following table summarizing the number of hours worked outside the home. Express the relative frequency as a percent. Class  Tally   Frequency    Relative Frequency  0-10 11-20 21-30 31-40 Total c. Find the five-number summary of the hours worked outside of the home by the 25 Berkeley College students.
