- Marine biologists have noticed that the color of the outermost growth band on a clam tends to be related to the time of year in which the clam dies. A biologist conducted a small investigation of whether this is true for the species Protothaca staminea. She collected a sample of 50 clam shells in February and 27 clam shells in March. 15 of the shells from February had a dark color on the outermost growth band, whereas 8 of the shells from March had a dark color on the outermost growth band. Carry out a hypothesis test to see if there is a difference in the proportion of shells with a dark outermost growth band between the two months. The point estimate for the true difference in proportion of dark growth bands between February and March is:Marine biologists have noticed that the color of the outermost growth band on a clam tends to be related to the time of year in which the clam dies.

- Marine biologists have noticed that the color of the outermost growth band on a clam tends to be related to the time of year in which the clam dies. A biologist conducted a small investigation of whether this is true for the species Protothaca staminea. She collected a sample of 55 clam shells in February and 55 clam shells in March. 14 of the shells from February had a dark color on the outermost growth band, whereas 8 of the shells from March had a dark color on the outermost growth band.

A 2009 survey of business owners indicated that 35% plan to provide a holiday gift to their employees (Radio, WEZV, Myrtle Beach, South Carolina,) Suppose the survey results are based on a sample of 60 business owners. Part A How many business owners in the survey plan to provide a holiday gift to their employees? Ans. Part B Suppose the business owners in the sample do as they plan. Compute the p-value for a hypothesis test that can be sued to determine if the proportion of business owners providing holiday gifts has decreased from the 2008 level.

- In a lumberjack competition, a contestant is blindfolded and spun around 9 times. The blindfolded contestant then tries to hit the target point in the middle of a horizontal log with an axe. The contestant receives 15 points if his hit is within 3 cm of the target, 10 points if his hit is between 3 cm and 10 cm of the target, 5 points if his hit is between 10 cm and 20 cm of the target, and Zero points if his hit is 20 cm or more away from the target. Let Y record the position of the hit, so that Y=y>0 corresponds to missing the target point to the right by y cm Y=-y<0 corresponds to missing the target to the left by y cm. Assume that Y is normally distributed with mean mu=0 and variance 100 cm2. Find the expected number of points that the contestant wins.define bionomial experiment.also dicus its properties with examplesQUESTION 17 DATAfile: NFLTeamValue In 2014, the 32 teams in the National Football League (NFL) were worth, on average, $1.17 billion, 5% more than in 2013.
