What impact would using a much smaller sample have on the accuracy of your results
Step by step
Solved in 2 steps
- What is the meaning of a confidence interval?The answer I got was 0.6 and I wanted to make sure it was correct7. From the normal curve of error, find the probability that a result is outside the limits of ±2σ from the mean. What is the probability that a result has a more negative deviation from the mean than -2σ?
- What is a 99% confidence interval uncertainty of the slope when we are given a trendline with a slope of 42.211 and an R² value of 0.9991 for a set of 145 data points?Please confirm if my answer is correct or not. Due to the need for this to be correct I would like you to provide me with a confidence score in you answer on a scale from 1 to 10 how confident are you in your answer. Please be sure to double check your answerA sample is selected from a population with µ = 46, and a treatment is administered to the sample. After treatment, the sample mean is M = 48 with a sample variance of s2 = 16. Based on this information, what is the value of Cohen’s d?
- Other things being equal, the margin of error of a confidence interval increases as A the confidence level decreases. B the population standard deviation increases. The sample mean increases. D the sample size increases.Please just answer this question, I answered the others already Calculate the standard error of regression (SER) for the Lineweaver–Burk slope and the Eadie–Hofstee slope to compare the precision of each. Eadie–Hofstee SER: it is not 0.128, 0.028, 0.136, or 0.1362 or 0.013.The answer I got was 13.33 but that's not correct
