An HR manager is selecting a random employee for a bonus. The probability that the employee works in Sales is 0.4. The probability that the employee works in IT is 0.3. No employee works in both departments. What is the probability that the selected employee works in Sales or IT? (Enter a decimal value.  For example, you would use .35, instead of 35%.)

A company wants to understand employee job satisfaction, but they use a survey that only asks about compensation. What kind of issue is this?

A marketing firm is estimating the average time users spend on their new app. They initially use a 90% confidence level. Later, they increase it to 99%. What will happen to the width of the confidence interval?

A data analyst works for a major airline.  She knows that the probability of a delayed flight is 0.21. What is the probability that a flight will NOT be delayed? (Enter a decimal value.  For example, you would use .35, instead of 35%.)

A web hosting company measures the average response time (in seconds) for a sample of 49 servers and finds a mean of 0.93 seconds and a standard deviation of 0.21 seconds. Find the 90% confidence interval for the mean response time.    (Use Z = 1.645)

What is the magnitude of the magnetic field at point C (y = 0.48 m) due to the current in the two cylinders?

The figure shows a cross section of three parallel wires each carrying a current of 24 A. The currents in wires B and C are out of the paper, while that in wire A is into the paper. If the distance R = 5.0 mm, what is the magnitude of the force on a 4.0-m length of wire A?

Assume that a uniform magnetic field is directed into this page. If an electron is released with an initial velocity directed from the bottom edge to the top edge of the page, which of the following describes the direction of the resultant force acting on the electron?

What is the current I2 in the other wire?

6) Select the sequence that is a Hamiltonian cycle for the graph shown below:
