find out probabilityof z score between -2.23 and 2.25
please only do: if you can teach explain each
Suzette does an experiment where she collects date from 5 women snd obtains the scores: 4, 4, 5, 2, 5. She hypothesizes that the population mean for the population from which these scores are drawn is 3. She wants to test whether this hypothesis is true. What is the alternative hypothesis she is testing?
the central limit theorem informs the numerator of the z- score for the sample means equation. true or false?
A local DMV (location of your choice) wanted to assess the number of mistakes that were made by its operators (aka clerks). One hundred samples were gathered from each of 20 operators (note: n = 100 for calculation of σp but you will need 100 * 20 to calculate p-bar). The results are shown in the table below. The DMV wants to set control limits to include 95% of the random variation. Operator # Number of errors Fraction defective Operator # Number of errors Fraction defective 1 6 11 6 2 5 12 1 3 0 13 8 4 1 14 7 5 4 15 5 6 2 16 4 7 5 17 11 8 3 18 3 9 3 19 0 10 2 20 4 Calculate p-bar and σp. Complete the fractions defective in chart. Compute the control limits and center line for a p-chart. Plot the fraction defective in a p-chart and decide if the performance of the operators is…

A new system is introduced and 10 hammer samples are drawn. Since the no. of samples is < 30, t-test must have been used. Please correct me if this interpretataion is wrong According to this flowchart, t-test must be used when the sample size is less than 30.
Mean, variance, standard deviation, & z-scores: {5, 7, 7, 5, 5} {7, 7, 11, 7, 10} N=5
The average wait time to get seated at a popular restaurant in the city on a Friday night is 12 minutes. Is the mean wait time different for men who wear a tie? Wait times for 14 randomly selected men who were wearing a tie are shown below. Assume that the distribution of the population is normal. 10, 13, 12, 12, 9, 12, 12, 13, 10, 11, 12, 13, 11, 10 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 answer v H1: ? v Select an answer v c. The test statistic ? v (please show your answer to 3 decimal places.) d. The p-value (Please show your answer to 4 decimal places.) e. The p-value is ? v a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the population mean is not significantly different from 12 at a = 0.10, so there is statistically insignificant evidence…
