PLEASE HELP WITH ALL THESE QUESTIONS THANKS(Q6:) What is the lower 95% confident limit of a sample of 20 mosquito fish with a mean of 21.0 and a standard deviation of 1.76?(Q7:) what percentage of means of sample size 10 would be as high or higher than what we observed?(Q8:) What percentage of mean would be equal to it lower than the one observed? The observed mean was 159.40

What is the upper 95% confidence interval of our theoretical distribution for n = 10 (u = 152.10, o = 19.64, n = 10)? What is the lower 95% confidence interval of our theoretical distribution for n = 10 (u = 152.10, o = 19.64, n = 10)? What is the upper 95% confidence interval of our theoretical distribution for n = 10, x = 159.4, and o = 19.64 (for this calculation assume that u is unknown and o is known)? What is the lower 95% confidence interval of our theoretical distribution for n = 10, x = 159.4, and o = 19.64 (for this calculation assume that u is unknown and o is known)? What is the upper 95% confidence limit of a sample of 20 mosquito fish with a mean (x) of 21.0 and a standard deviation (s) of 1.76. Use the t-distribution for this one and all future ones
