Need help finding test statistic, p-value, and confidence interval, please. Thank you very much!! Professors collected data consisting of eye color and gender of statistics students. Among 913 male students, 288 had blue eyes. Among 1105 female students, 356 had blue eyes. Use a 0.05significance level to test the claim that the proportions of blue eyes are the same for males and females. Complete parts (a) through (c) below. Consider the first sample to be the sample of malesand the second sample to be the sample of females.a. Test the claim using a hypothesis test.What are the null and alternative hypotheses for the hypothesis test?A. Ho: P₁2P2H₁: P1 P2D.

can someone explain how I do this problem? I'm lost and keep messing up, I only have 2 more tries to get it correct, thanks
find the point esitmate, the standard error, the margin of error for the given confidence levels of x and n x = 29, n = 80, confidence level 92% show your work
Please do not give solution in image format thanku
In a survey conducted in a certain city it was found that 4.6% of men and 5.4% of women were unemployed. The margin of error for each report was 0.6 percentage points. Use each sample statistic to find a Confidence interval. (Show your confidence interval calculation for full credit) Can we conclude that the unemployment rate is higher among women than among men? Explain your response in a sentence. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac). BIUS Paragraph Arial 14px Ix II
help please answer in text form with proper workings and explanation for each and every part and steps with concept and introduction no AI no copy paste remember answer must be in proper format with all working
Hi Team, Please provide answer for part B as well, Thanks a lot for all the help.
It is known that the mean cholesterol level for all Americans is 190 construct the relevant hypothesis test to show that only children have an average higher cholesterol level than the national average. We test 100 only children and find out the mean is 198. You can use your own confidence level.(all American standard division is 15)
Please show the excel sheet if possible. Thanks
could you please tell me how to explain to a friend who does not know anything about statistics the relationship between the confidence level expressed as a confidence interval and the level of significance in hypothesis testing. Illustrate the relationship using either the critical value or the p-value approach.thanks
Congratulations, you just made a confidence interval! But wait, how did we decide on the width of the interval? The middle of the interval is the sample mean. We start there, and then the "wiggle room" we give on either side of that center is called the margin of error (MOE). There's a formula for margin of error: 0 MOE = 2* √T This formula consists of three values: o is the standard deviation, n is the sample size, and z is a multiplier that we choose based on the confidence level we need. Confidence levels are expressed as percentages, the most common are 90%, 95%, and 99%: * Confidence Z Level value 90% 1.645 95% 1.96 99% 2.576 Let's practice computing a margin of error. For our earlier example about houses, suppose the standard deviation was 14 years, and the sample size was 30. Use a confidence level of 95% and determine the margin of error: σ Remember, we'll use the formula MOE = 2* . First fill in the numbers for each part of the formula: √n = σ= n = Now put it all together,…
A medication is undergoing a clinical trial. They have taken the blood pressure of the participants on n=25 occasions. The mean blood pressure was 132 systolic for the participants with a standard deviation of 3 points. Construct a 90% and 95% confidence interval for the true mean systolic pressure. Interpret the confidence interval in your own words. Do you think this drug is effective based on the confidence interval? Why or why not?
