If n=41, ¯x=39, and s=16, construct a confidence interval at a 99% confidence level. Assume the data came from a normally distributed population

CNN is conducting a poll, and wants to produce a 90% confidence interval for the proportion of all New York residents who favor legalizing recreational marijuana. Of the 602 randomly selected New Yorkers surveyed, 394 were in favor of the initiative. a.   With 90% confidence, the proportion of New York residents who favor legalizing recreational marijuana is between  BLANK and BLANK.  b.   Suppose that we survey 602 randomly selected Americans many times, and calculate a confidence interval for each group. About Blank . percent of these confidence intervals will contain the true population proportion of New Yorkers who favor legalizing recreational marijuana, and about BLANK   percent will not contain the true population proportion.

A researcher reports t(5) = +3.00, p < .05 for a repeated-measures research study. The mean sample difference score for the sample was MD = 12. Which of the following is the confidence interval for the population mean difference?

A survey of 2450 golfers showed that 281 of them are left-handed. Construct a 90% confidence interval for the proportion of golfers that are left-handed. Question 10 options: (0.104, 0.125) (0.369, 0.451) (0.100, 0.130) (0.203, 0.293)

If n=31, (x-bar)=36, and S3D3, construct a confidence interval at a 95% confidence level. Assume the data came from a normally distributed population. Give your answers to one decimal place.

The class collected their data and found the mean of the dominant forearm maximum force was 34.2 +-3.4 kg . The mean non-dominant forearm maximum force was 28.5 +- 7.8 kg for their 95% confidence intervals. Would you conclude that the means are different?

50 of the 600 medical students who were chosen at random stated they intended to work in a rural area. Calculate the 90% confidence interval for the actual percentage of medical students who intend to practice in rural areas. The responses shown here are estimates.
