If a stratified random sample of 200 nursing students is extracted from a gender-stratified population containing 90% women and 10% men, how many men will this sample have?
Homework Answers
here as we know that for stratified sampling we draw proportionate data from each strata
therefore expected number of men in the sample =np=200*0.9 =180

You are interested in wage gender differences. You have a random sample of the population. The sample mean hourly wage for men is KSH 22 while it is KSH 19 for women. The standard deviations of these samples are respectively, 6.1 and 7.1. How can you calculate the standard error of the difference in means? A. It is (6.1/number of men in the sample) + (7.1/number of women in the sample) B. It is the square root of (7.1 –...

Random sample of 100 students from a population 46,000. In this survey we have 58 females and 42 males. Is there an equal portion of men and women in the population? Show that the conditions are met for the use of a normal model for a hypothesis test (np is greater than or equal to 10 and n(1-p) greater than or equal to 10, where p is from the null hypothesis.

A random sample of size 90 is selected from a population of over 2,000 students. The sample is measured on an achievement test and the mean score on the test is 79.5. The difference between the sample mean and the population mean is due to: sampling bias sampling error the sampling fraction sampling stratification Sampling bias is variation caused by random fluctuation.

Sociologists have conducted much interesting research on gender stereotypes in American society. A curious aspect of stereotypes is that people tend to perceive differences between groups to be greater than they actually are. This suggests, for example, that when asked about the heights of men and women, survey respondents would tend to perceive men to be taller than women. Suppose you wanted to test this notion that individuals perceive a greater height difference between man and women than exists in...
