- Because most data vaules are on the left of a graph, we would say that a dot plot shows a distribution that is skewed to the left? it will be true correctWhat are some examples of measures that you think may be normally distributed? In general, what does the distribution of a measure need to look like for it to be normally distributed?Find the variance if X~N(0, 7) and 95% of the data are between -7 and 7.
- What are the functions of averages?for normal distribution mean is 50 liter per hour and standard deviation is 10 liter per hours . find the 68%,95%and 99.7% values by using emperical graph explain graph with all valuesPost your created histogram. How would you describe the distribution? (Symmetric, skew left, skew right? Is it unimodal or bimodal?) Picture is below .

Is the average smaller for college students? The data below shows the results of a survey of 15 college students asking them how many days elapse between haircuts. Assume that the distribution of the population is normal. 35, 23, 32, 38, 31, 39, 35, 25, 30, 36, 40, 27, 23, 32, 25 What can be concluded at the the a = 0.10 level of significance level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ?v Select an answerv Hi: ?vSelect an answerv c. The test statistic ?v = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 3 decimal places.) e. The p-value is 2v a f. Based on this, we should Select an answerv the null hypothesis. g. Thus, the final conclusion is that..

- Please state if the statement is correct or wrong and explain why. Statement 1. The sampling distribution of the sample mean with a sample size of 12 has a smaller standard error than that of the sampling distribution of the sample mean with a sample size of 13. Statement 2. Degrees of Freedom is one of the parameters of the normal distribution. Statement 3. A parameter is a function of a sample.Use the Histogram tool to develop a frequency distribution and histogram for the number of months as a customer of the bank in the data below.
