1. Question: A coin is flipped 30 times. What is the probability of getting 15 or more heads? Round answer to 4 decimal places. 2. Question: It is known that 50% of adult workers have a high school diploma. If a random sample of 8 adult workers is selected, what is the probability that less than 6 of them have a high school diploma? 3. Question: If random variable X has a binomial distribution with n=9 and P(success) =p= 0.4, find the standard deviation of X. 4. Question: If random variable X...

1. Problem 15-27 (Algorithmic): Gubser Welding, Inc., operates a welding service for construction and automotive repair jobs. Assume that the arrival of jobs at the company's office can be described by a Poisson probability distribution with an arrival rate of three jobs per 8-hour day. The time required to complete the jobs follows a normal probability distribution, with a mean time of 2.2 hours and a standard deviation of 1 hour. Answer the following questions, assuming that Gubser uses one w...

Logistic Regression - Commonly used for modeling binary response data. The response variable is a binary variable, and thus, not normally distributed. In logistic regression, we model the probability of a success, not the response variable. In this model, we do not have an error term g-function - We link the probability of success to the predicting variables using the g link function. The g function is the s-shape function that models the probability of success with respect to the predict...
