Show me how to solve the problem Newborn elephant calves usually weigh between 200 and 250 pounds-until October 2006, that is. An Asian elephant at the Houston (Texas) Zoo give birth to a male calf weighing in at a whopping 384 pounds! Mack (like the truck) is believed to be the heaviest elephant calf ever born at a facility accredited by the Association of Zoos and Aquariums. If, indeed, the mean wight for newborn elephant calves is 225 pounds with a standard deviation of 45 pounds, what is the probability of a newborn weighing at least 384 pounds? Assume that the weighs of newborn elephants are normally distributed.
A retail grocer has decided to market organic "health foods" and will purchase a new line of products from each of two suppliers. Unknown to the grocer
Women have been on a diet within the past 12 months. Using Normal approximation, what is the probability (±0.001) that 76% or more of the women in the sample have been on a diet?
You want to determine if your widgets from machine 1 are the same as machine 2. Machine 1 has a sample mean of 50 and a population standard deviation of 5 and a sample size of 25.
Such that setting the two equations together we see that at t=4 seconds, the distance that Peter travelled is the same as the distance of the room 40ft.
Mean=63.6 Standard deviation=2.5 If 36 data points are arbitrarily chosen, determine the probability that mean is less than 64.
Ten people agree to take part in an experiment designed to determine whether a persons weight differs between morning & evening.
How many individuals will it need to sample to achieve this level of accuracy and confidence?
A sample of 8 jars has a mean of 15.6 ounces and a standard deviation of 0.3 ounce. Is there enough evidence to support the consumer's conjecture at a = 0.05 and how can this be graphed?
