Law enforcement officers want to know if the average driver is speeding (driving faster than the posted speed limit) on a local highway with a posted speed limit of 70 mph. To test this, they select a sample of 49 drivers and find a sample mean speed of 74 mph, with a standard deviation of 15 mph.    At 95% confidence, perform a 7-step hypothesis test of law enforcement’s question. [Show all 7 steps, but do not worry about inserting Greek letters, using the equation editor, etc.]    

Describe in one sentence each, what the active, saturation and cutoff modes in a transistor are used for. A very short answer for each will do for this one.

Explain why an amplifier’s input AND output impedance characteristics are important and what size is ideal for EACH. What would happen if these values were not ideal?  Also discuss a situation in which you would want matched impedances (that is, output impedance of the first stage equal to input impedance of the second).

What does this circuit do? When would it be used?

Based on this client statement, determine which stage of change he or she is in: “I know what you are going to tell me, and I know a lot about nutrition. I know what I need to do to lose weight, but I just can’t do it.”

Explain the difference between implicit and explicit intents in Android. Provide an example for each.

You are working with a client to reduce blood sugar levels. The client has many family members with diabetes and is very knowledgeable about carbohydrate counting.  The client is able to think critically and devise healthy meal plans, but has moderate readiness in independently following the nutrition care plan. To be most effective in meeting the client’s needs, what would be the best approach?

According to the self-determination theory, which of the following is not one of the factors that influences motivation?

Which of the following is one octave away from 40Hz? Mark all that apply

Suppose you estimate the following regression equation (y-hat line) relating the “tastiness score” of chocolate candies to the number of calories in a serving, whether the candy contains nuts, and whether the candy is from a U.S. candy maker:  TASTE = 30 + 0.25CALORIE + 5NUT – 3U.S.  [TASTE = overall taste rating, 0-to-100, CALORIE = number of calories per serving, NUT is a dummy variable equal to 1 if the candy contains nuts (0 otherwise), and U.S. is a dummy variable equal to 1 if the candy is from an American candy maker (0 otherwise).]  Question: Interpret, precisely, the coefficient on NUT from the regression equation above.
