The Chi-Square goodness of fit test to test whether thenormality assumption is true for column 1 is performed in followingsteps in excel.Step 1: Write the data value in excel. The screenshot is shownbelow,AStep 2: The mean and standard deviation for the data values areobtained using the excel functions =AVERAGE() and STDEV(). Thescreenshot is shown below,Step 3: The Z score for each data values are obtained using theformula,Z score =(X-mu)/(sigma)The screenshot is shown below,Step 4: The observed value are obtained by counting the Z scoreas follows,The observed values are,Observed valuesZ scoreCountZ&lt;-14-1&lt;Z&lt;050&lt;Z&lt;18Z&gt;13Step 5: The expected values are obtained in excel. Thescreenshot is shown below,The expected values are,Expected valuesZ scoreCountZ&lt;-13.173-1&lt;Z&lt;06.8270&lt;Z&lt;16.827Z&gt;13.173Step 6: The Chi-Square statistic is obtained using theformula,chi^(2)=sum((" Observed-Expected ")^(2))/(" Expected ")Z scoreObserved, <img alt="0" src="https://studymeta.oss-cn-hongkong.aliyuncs.com/9/9d14353e1ec1eee5e65b97ca7c21f2fd.jpg" aria-describe ...

What side of the bed do you get out of when you wake up? An analyst asked a random sample of 80 teenagers what side of the bed they get out of and 52 said that they get out of the right side of the bed. Construct and interpret a 90% confidence interval for the proportion of all teenagers that get out of the right side of the bed. STATE: 90% CI for = the of teenagers that get out of the right side of the bed. PLAN: Select 3 true statements. The sample size, 80, is less than 10% of all teenagers. We have a random sample of 80 teenagers The Random condition is not met. One-sample z interval for u The 10% condition is not met. One-sample z interval for p Large Counts: no = n(1 - 2) = The Large Counts condition met because the number of successes, np, and the number of failures, n(1-P), both at least 10. DO: DO: p = (Enter 2 decimal places) (Enter 3 decimal places) The 90% CI is ( ). CONCLUDE: We are 90% confident that the interval from to captures = the of all teenagers that get out of the right side of the bed.
Show that if A and B are matrices which don’t commute, then eA+B = eAeB, but if they do commute then the relation holds. Hint: Write out several terms of the infinite series for eA, eB, and eA+B and do the multiplications carefully assuming that A and B don’t commute. Then see what happens if they do commute.
