4. [12 pts] From all students taking Elementary Stat at Brockport, a common test has revealed a normal distribution with mean 72 and standard deviation of 6.5. a.) Find the probability that a single randomly selected student has scored more than 75. b.) Find the probability that a single randomly selected student has scored less than 62 c.) You then select a random sample of 25 students that took the test. - Compute the probability that the sample mean is greater than 75 - Compute the probability that the sample mean is less than 65 - Compute the probability that the sample mean is between 65 and 75. - Construct a 98% confidence interval for the student population mean for the test, and interpret.

GMM and Panel Data Models 2. Use the \"JTRAIN.dta\" database and consider the following equation: $\log(scrap) = b_0 + b_1 union + d88 + d89 + b_2hrsemp + cX + e$ where 'scrap' represents the rate of broken products for company I in year t, union is a dummy variable indicating whether the company is affiliated with a union, d88 and d89 are dummies for those years, and hrsemp represents the training hours per employee. a) Choose additional control variables for X and justify your model choice. b) Under what assumptions is 'grant' (an indicator whether the company received a grant) a good instrument for the variable 'hrsemp'? c) Retrieve the weight matrix after GMM estimation and define any other matrices necessary to calculate the estimated value of the criterion function. d) Use the value of the criterion function to perform the Sargan-Hansen test. e) Replicate the estimation in (a) using two linear regressions. What are the differences between the estimation and the results here and in (a)? f) Conduct a test for the instrument's relevance and re-estimate the equation using first differences with the instrumental variable. Discuss your results and compare them with the previous ones.

QUESTION36: Which sequence of events best describes how a local potential is produced? Ligand-gated channels open and Na+ enters the cell. A stimulus is present (pain, temperature). Chemicals are released in response to the stimulus and attach to ligand-gated channels. The Na+ ion travels on the inside of the membrane to the trigger zone and forms a local potential. QUESTION37: Ascending tracts send signals from the point of stimulation to the brain via upper and lower motor neurons, decussating neurons, and chains of unmyelinated ventral motor neurons. QUESTION38: The body deals with stress (GAS). True.
