The mean class grade for all health sciences statistics students from previous semesters was 85% with a standard deviation of 7%. We want to know if the current class of statistics students is significantly different from the previous years’ population. The current mean class grade is 87% with a standard deviation of 5%. There are 30 students in the class. Use α = .10. a. What is the SEM? b. What is the critical value? c. What is the one-sample...

Consider a 7-month forward contract on a stock with a current price of $80. We assume that the risk-free interest rate continuously compounded is 7.5% p.a. for all maturities. We also assume that dividends of $1 are expected after three months and six months. a) What should be the theoretical forward price? b) If the forward price is $81, use a cash ow table that is similar to what we learned in class to show how you would arbitrage from...

A teacher wants to determine why students signed up for his summer statistics class. He asked a randomly selected 50 (of the 275) registered to select one of four reasons (convenience, liked his teaching style, needed it to graduate, or other) on an online quiz. Identify the experimental unit of interest to this problem a-The question he asked to the 50 students b-The 50 students he collected information from. c-A single student registered in his summer class d-All 275 students...

In an absolutely hypothetical scenario and a cruel world, the professor is grading the students through the following model: The students will receive a grade based on the outcome of drawing a ball from a bag. Consider the bag containing 60 lottery balls, numbering from 1 to 60. Additionally, each ball is either white or red; all the odd-numbered balls are white, and all the even-numbered balls are red. If a student draws a white ball, he/she will also be...

Consider a scenario where you have two samples. Sample 1 contains 50 observations, has the sample average value of 38 and the sample standard deviation of 2.5. Sample 2 contains 50 observations, has the sample average of 39 and the sample standard deviation of 2.0. Based on this information, please conduct a 95% significance test for the equality of the two population means. Note that we don’t know the population standard deviations but we CAN assume that they are equal....

A math teacher, wanting to assess students 'knowledge, put in a competition in which students' performance averaged 65 (with an excellent 100) and a standard deviation of 10 units. Let's consider that the distribution of performance is normal: A. Find the probability that the performance of a randomly selected student is over 75. B. If we consider that the random variable that describes student performance is continuous (that is, it can take any real value between 0 and 100 and...

We typically consider cases in class where charge is distributed completely uniformly, but it's not always that way - let's consider an insulating sphere (radius R) with surface charge density s =s0 sin2(q) cos2(f). (a) Describe briefly in words and a picture what this charge distribution "looks like" – i.e. where on the sphere is there more charge and where is there is less charge. (b) Set up an integral for the total charge on this sphere in terms of...
