1. In the past, it was believed that 40% of women felt that men are basically selfish and self-centered. It is now claimed that this proportion has increased. A sample of 3,000 women shows that 1,260 agree with this statement. Can the statistician conclude that more than 40% of women felt that men are basically selfish and self-centered? Use ά = 0.05.2.

Intermediate Statistics and Research Methods Q8
A simple random sample of pulse rates of 50 women from a normally distributed population results in a standard deviation of 12.1 beats per minute. The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with a 0.05 significance level to test the claim that pulse...

Test the given claim. Use the P-value method or the traditional method as indicated. Identify the null hypothesis, alternative hypothesis, test statistic, critical value(s) or P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. The mean resting pulse rate for men is 72 beats per minute. A simple random sample of men who regularly work out at Mitch's Gym is obtained and their resting pulse rates (in beats per minute) are listed below. Use a...

280 men are found to have an average pulse rate of 73 (beats per minute) with standard deviation 5.4, and 240 women are found to have an average pulse rate of 72 (beats per minute) with standard deviation 7.7. A researcher is interested in whether, on average, men have higher pulse rates than women. What is the most appropriate test for the researcher to use? a. z-test for the difference between two proportions b. chi-squared test c. two sample t-test...
