Question
Post & Discuss Post your four paragraph (maximum) article critique, include your article as an attachment (or a link to the article), and then address the following: . Do you believe the results? Why or why not? . State the reported confidence interval(s) estimate in two ways: o the upper and lower limits the sample proportion ± the error term (don't forget to include the confidence level) . State the meaning of the confidence interval(s). . Can a reported mean of your article data be treated as a value from a population having a normal distribution? Why or why not? You should make your initial post before the fourth day of the module week to receive full credit. Return at least once later in the module week to provide meaningful comments to two or more of your classmates' posts. DO | NOT “post and run. making all three posts in the same visit. You need multiple visits to the discussion area to gain multiple perspectives by reading all of the posts and replies. Review the Discussion Rubric for detailed grading information.Explanation / Answer
1) do You belive thé results ? Why or Why not ?
Ans:-If we are assuming, claiming or making any statement regarding any of the experiment their is need of results.
Yes , I belive in results.
2)state thé reported confidence Interval (s) estimate in Two ways.
Ans:- confidence Interval - à range of numbers around thé point estimate Within which thé parameter is belived to fall
Point estimate - mean of data , average
We have 95% 90% 99% confidence intervals
These 95% 90% 99% are confidence levels.
Confidence Interval for thé poppulation mean is
95% C. I.
Lower limit =x bar -1.96 * standard error
Upper limit = x bar +1.96 * standard error
3)meaning of confidence interval
Ans:- confidence Interval tells You How accurate your estimate of the mean is likely To be.
4)can à reported mean of your article data be treated as a value from à poppulation having à normal distribution ? Why or Why not ?
Ans:-yes , reported mean is from Normally distributed poppulation.
100(1-alpha) C. I. For a normal poppulation mean u
Where point estimate u
Standard Error =sigma /square root (n)
And Z(alpha/2) is found in normal distribution.
