Exercises 49-54 deal with sickle cell anemia, an inherited disease in which red blood cells become distorted and deprived of oxygen. Approximately 1 in every 500 African-American infants is born with the disease; only I in 160,000 white infants has the disease. A person with two sickle cell genes will have the disease, but a person with only one sickle cell gene will have a mild, nonfatal anemia called sickle cell trait. (Approximately 8%-10% of the African-American population has this trait.) Second Parent S s First S SS Ss Parent s sS ss If we use s to represent a sickle cell gene and S a healthy gene, the above table shows the four possibilities for the children of two Ss parents. Each parent has only one sickle cell gene, so each has the relatively mild sickle cell trait. Find the probability that these parents give birth to a child who has sickle cell trait.

Solution Summary: The author explains that the probability of a child having sickle cell trait is 12.

A rodentologist investigating various aspects of the aging process wanted to see whether staying “lean and mean” that is, being under normal body weight would lengthen life span. She randomly assigned newborn rats from a highly inbred line to one of three diets: (1) unlimited access to food, (2) 90% of the amount of food that a rat of that size would normally eat, (3) 80% of the amount of food that a rat of that size would normally eat. She maintained the rats on the three diets throughout their lives and recorded their life spans (in years). Complete a Turkey's post HOC test to determine which one is significantly different
In clinical trials, 60 percent of new cancer drugs advance from Phase I to Phase II, 25 percent advance from Phase II to Phase III, and 80 percent advance from Phase III to Phase IV. If 100 new drugs are entered into clinical trials, how many are expected to make it to Phase IV?
According to a study administered by the National Bureau of Economic Research, half of Americans would struggle to come up with $2000$2000 in the event of a financial emergency. The majority of the 19001900 Americans surveyed said they would rely on more than one method to come up with emergency funds if required. In the survey, 397397 people said that they "certainly" would not be able to cope with an unexpected $2000$2000 bill if they had to come up with the money in 3030 days, and 553553 people said they "probably" would not be able to cope.
Step 2 of 2 :
What percentage of Americans would "probably" not be able to pay a $2000$2000 bill in 3030 days if required? Round your answer to one decimal place, if necessary.
