Answer the following, rounding off your answer to three decimal places. (a) What is the sample mean? (b) What is the sample standard deviation? (c) What is the test statistic used in the decision rule? (d) What is the critical value? (e) Can the null hypothesis be rejected at a 5% significance level? O A. Do not reject the null hypothesis. O B. Reject the null hypothesis. Submit answer Next item

In June 2003, frantic parents rushed a 3-month-old female infant to the emergency room of a regional medical center in rural Tennessee. On initial examination by a triage nurse, "Baby Caroline" appeared listless with unfocused eyes and labored breathing. Her parents reported that, over the past 72 hours, the infant had grown increasingly irritable and had cried weakly and seemed unable to nurse properly. Further questioning revealed that Baby Caroline had had no bowel movements for 3 days. Within 48 hours of admission, she developed flaccid paralysis and experienced respiratory failure. The child received supportive therapy, including the use of a ventilator and administration of antitoxin. Full recovery occurred in about 4 weeks. Which of the following diseases is likely indicated in this case? O tetanus Obotulism Staphylococcal Scaled Skin Syndrome (SSSS) O impetigo Oviral meningitis

4. Two blocks of masses M = 5kg and 3M are placed on a horizontal, frictionless surface. A light spring is attached to one of them, and the blocks are pushed together with the spring between them (see figure). A cord initially holding the blocks together is burned; after that happens, the block of mass 3M moves to the right with a speed of 2.00 \frac{m}{s}. (a) What is the velocity of the block of mass M? (b) What was the energy stored in the spring? (Hint: Where did the blocks get their kinetic energy?)

A builder calculated an approximate 99.7% confidence interval for the population mean price for houses, based on the following sample data: From a sample of 1600 houses, the sample mean price is $300,000. Assume the population standard deviation is $11,726. What is the confidence interval? Assume the distribution of home prices is normally distributed. Enter your answer in the format (lower, upper) where "lower" is the lower confidence limit and "upper" is the upper confidence limit. Round each numerical input.
