Prelab Procedure: You will use either oxalic acid or citric acid. Determine the amount of solid acid you need prior to class to complete the titration with one full buret. You will use the exact concentration of NaOH you determined a couple of weeks ago. (Turn in the calculations for the amount of acid to use with your pre-lab questions.) Conc.

ou are interested in the average emergency room (ER) wait time at your local hospital. It is known that average ER wait time is normally distributed. You take a random sample of 50 patients who visit the ER over the past week. From this sample, the mean wait time was 30 minutes and the standard deviation was 20 minutes. Find a 92% confidence interval for the average ER wait time for the hospital.
m 5 n 45° Find the value of the variables in the figure above. Give your answers as a decimal rounded to the nearest tenth and as a radical (reduced if possible). If there is no radical answer, leave the answer blank. Decimal: $m = 5$ Radical: $m = $ Decimal: $n = $ Radical: $n = $ Submit Question
6. The management of Green Technologies is considering a new technique for manufacturing its solar panels. The current method requires 55.8 minutes to produce a panel. The mean production time for a random sample of 30 panels, using the new technique, was 53.1 minutes, and the standard deviation of the sample was 3.4 minutes. Can we conclude that the production time using the new technique is faster at the 1% significance level?
