Let z represent the standard normal variable and suppose a value is randomly selected. Find each of the following probabilities by:
i) Drawing the standard normal curve and indicating the area representing the probability and
ii) Calculating the probability using P (-1.49 < z < 1.35).
Find out the constant using probability density function also cumulative distribution function. Assume X be a continuous random variable with probability density function.
Choose the proper conclusion regarding the claim that the population have different variances.
More than 13 successes in 19 trials with a 40 percent chance of success. (Round the answer to 4 decimal places.) Fewer than 7 successes in 15 trials with a 40 percent chance of success. (Round the answer to 4 decimal places.)
Using the original data, test at the 5% significance level that the population standard deviation of studying times is greater than 4 hours.
The estimated simple linear regression equation minimizes the sum of the squared deviations between each value of Y and the line.
Draw a normal probability plot for residuals using excel or Minitab. Do the residuals seem normally distributed? If yes, why?
The mean assembly time for a random sample of 24 carts, using the new method, was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes.
Times spent studying by students in the week before final exams follow a normal distribution with standard deviation 8 hours. A random sample of four students was taken in order to estimate the mean study time for the population of all students.
It is suspected that the mean turnover has changed and is not 6.0. Use the .05 significance level. State the null hypothesis and the alternate hypothesis.
State the values of the coefficient of correlation and coefficient of determination correct to three decimal places
MATH1550H: Assignment: Questions: Let’s assume the department of Mathematics of Trent University has 11 faculty members. For i = 0; 1; 2; 3; find pi, the probability that i of them were born on Canada Day using the binomial distributions.
