A manufacturing company regularly conducts quality control checks at specified periods on the products it manufactures. Historically, the failure rate for LED light bulbs that the company manufactures is 4%. Suppose a random sample of 10 LED light bulbs is selected. Complete parts (a) through (d) below. a. What is the probability that none of the LED light bulbs are defective? The probability that none of the LED light bulbs are defective is 0.6648. Type an integer or a decimal. Round to four decimal places as needed.) . What is the probability that exactly one of the LED light bulbs is defective? The probability that exactly one of the LED light bulbs is defective is 0.2770. Type an integer or a decimal. Round to four decimal places as needed.) c. What is the probability that three or fewer of the LED light bulbs are defective? The probability that three or fewer of the LED light bulbs are defective is. Type an integer or a decimal. Round to four decimal places as needed.)

Researchers wants to determine if low-fat diets or low-carb diets are more effective for weight loss. Suppose 100 people were placed on a low-fat diet and at the end of 3 months the mean weight loss was 10.5 lbs witha standard deviation of 12.5 lbs. There were another 100 people placed on a low-carb diet and at the end of 3 months the mean weight loss was 16.5 lbs with a standard deviation of 10.2 lbs. Does mean weight lossdiffer between the two diets? What are the hypotheses??
