I need the test statistic and p value too Thankyou.
Suppose your statistics professor gave six examinations during the semester. You received the following exam scores (percent correct): 79, 84, 82, 82, 84 and 77. To compute your final course grade, the professor decided to randomly select two exam scores, compute their mean, and use this score to determine your final course grade.i. List all possible samples of size 2 and compute the mean of each.ii. Compare mean of sample means to the population mean.
For the (x , y) data set (−3,−2),(1,1),(5,4),(8,6),(11,10), find interval estimates (at a 98% confidence level) for single value and for the mean value of ?y corresponding to x=1. Note: For each part below, your answer should use interval notation. Interval Estimate for Single Value = Interval Estimate for Mean Value =
(c) 300 mg. 5-12. Find the mean and median of each of the following sets of data. Determine the deviation from the mean for each data point within the sets and find the mean devi- ation for each set.

The sample data here is the cholesterol levels for 10 men diagnosed with high cholesterol. The first row represents levels from 10 men who did not use the drug and the second row from 10 different men who did use the drug. If we want to test the claim that the mean level for all men who use the drug is less than the mean for all men who do not use it, using the MS Excel output table below, what is the conclusion of the test at 5 % level of significance? No Drug 237 289 257 228 303 275 262 304 244 233 Drug 194 240 230 186 265 222 242 281 240 212 There is enough evidence that men who use the drug have less cholesterol levels than those men who do not use the drug. There is not enough evidence that a significant difference exists between males who use the medicine and men who do not use the drug in terms of mean cholesterol levels. There is not enough evidence men who use the drug have less cholesterol levels than men who do not use the drug.…
Compare and contrast the two samples measures of central tendency. Compare and contrast the two samples of variation. What would you expect to the be the average height of all of the players? What would you expect the range of the height to be of all of the players?
You are the product manager for "Natural Agriculture". The company president asked you to determine if "Natural Agriculture" has equal sales as "Farmers Co.", which is a strong competitor. The table below contains weekly sales for competing brands for randomly selected 4 approximately equal size stores that did not follow a normal distribution. (Use two digits after deimal point) Natural Farmers Co. Agriculture 2100 2600 1700 1500 1900 1700 1500 2100 Is there a difference between mean sales at a=5%? а. Но: H;: Since test statistic = is than critical value = we and Therefore mean sales are b. Can it be concluded at 5% significance level that the population median sales for Farmers Co. exceeds 1900? Ho: H;: test statistic = Since a=0.05 is than the p-value = and There is evidence to we
Which of the following Z values would you use to calculate the 95% confidence interval? 1.28 1.96 1.645 2.58
please help me to solve this question. thank you!!!
Please answer all parts. Thanks so much.
There is a population of test scores. You take a sample of 11 scores and use them to estimate the population mean and standard deviation. Then you compute a 95% confidence interval for the mean. This confidence interval contains values that are within how many standard deviations of its mean?
The claim that the proportion of accidental deaths of the ederly attribute to resident falls is more than 0.20, and the sample statistics include 60 deaths of the ederly with 15% of them attributable to resident falls. find the value of the test statistic z.
