2.(2 - TABLE) According to U.S.D.Agriculture, the mean calorie intake of male 20 to 29 years old is 2716, with standard deviation of 73.5. Suppose a nutritionist analizes a simple random sample of n = 35 males between the ages of 20 and 39 years old and obtains a sample mean calorie intake of 2735 calories. a) central tendency and dispersion. Check the condition and describe the sampling distribution. You should provide the measeures of b) would result in a sample mean of 2735 calories or higher? What is the probability that a random sample of 35 males between the ages of 20 and 39 years old (z - TABLE) The mean incubation time of fertilized chicken eggs kept at 110.50° F in a still-air incubator is 21.49 days with standard deviation of 1.21 day. What is the probability that a randomly selected egg has incubation time more than 23 days ? 3.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
