How do I use Student's t-Test at a 95% confidence interval to see if a slope is negative positive or zero. n=infinity so t=1.960. The slope is -0.0007 and has an uncertainty of 0.00005 and n=2120 so standard deivation of the slope is 0.0023
Inference of the population mean with small samples
Show development for the solution
In an clinic, a certain group of people is on a program to lose weight and improve their health. At the end of the program and as a result of a random sample of 10 patients, it was obtained that the average weight loss was 15.9 with a standard deviation of 5.3.
a) Construct a 95% confidence interval for the population mean of the weight loss program.
b) If the clinic expects people to lose an average of 14 kilograms with the program, do you think the program is adequate? justifies
c) What sample size would you recommend the clinic use if they want to have a confidence level of 99% and a margin of error of 2 kilograms?
A confidence interval for a population parameter:
(a) Gives possible values that the true population parameter will be within at a certain level of confidence.

(c) Gives possible values the true population parameter will be within with 100% confidence.
(d) Gives one possible value the true population parameter will be with a certain level of confidence.

- CONFIDENCE INTERVALS FOR THE DIFFERENCE IN 2 POPULATION PROPORTIONS Pharmaceutical scientists tested the effectiveness of a new drug designed to cure malaria. They recorded the proportion of rats that were cured when given the existing drug (sample 1 proportion) and the proportion of rats that were cured when given the new drug (sample 2 proportion). The 95% confidence interval for the difference in the proportion of cured rats between these two groups was (-0.18, -.005). Interpret this interval. O p1 is substantially more than p2, therefore we can be 95% confident that the proportion of rats cured is substantially higher when given the existing drug verses the new drug. O p1 is substantially less than p2, therefore we can be 95% confident that the proportion of rats cured is substantially higher when given the new drug verses the existing drug. O p1 is similar to p2, therefore we can be 95% confident that the proportion of rats cured is similar, whether given the new drug or the…arrow_forwardConfidence Interval Assume that we will use the sample data from Exercise 1 with a 0.05 significance level in a test of the claim that the population mean is greater than 90 sec.
