See image for question. Choose one of the answer options below:D. Since it is close to normal with a smaller standard deviationC. Since it is still bimodal with a similar standard deviationB. Since it is close to normal with a similar standard deviationA. Since it is still bimodal but with a smaller standard deviation A hypothetical distribution for a population of test scores is displayedbelow. The population has a mean of 60.4, a median of 62.8, and astandard deviation of 6.404. Each of the other four graphs labeled A toD represents possible distributions of sample means for randomsamples drawn from the population.Which graph best represents a distribution of sample means for 1000samples of size 100?POPULAT7MB11

A real estate agent claims that mean household incomes in Fairfax and Arlington are equal. Draw 32 residents randomly from Fairfax neighborhood we found the average income is $82,750 with population standard deviation $2900; while from 30 Arlington residents, the average income 81,200 with with population deviation $2225. f you don't trust its claim, what is the H 0, and what is the H a ? If you support its claim, what is the H 0, and what is the H a ?
John wishes to estimate the population standard deviation of salary of college graduates who took a statistics course in college. How many college graduates must he survey? Assume that he wants to be the sample standard deviation to be within 1% of the population standard deviation and to be 99% confident of that statement.
A California lake has been stocked with rainbow trout. These trout have an average length of 24 inches, with a standard deviation of 3 inches. Someone goes fishing and catches a trout that is 26.25 inches long. Express the length of this trout in standard units, relative to all the trout that were used to stock the lake. Choose the answer below that is closest.

Solve the problem. The systolic blood pressures of the patients at a hospital are normally distributed with a mean of 138 mmHg and a standard deviation of 12.8 mmHg. Find the two blood pressures having these properties: the mean is midway between them and 90 % of all blood pressures are between them. (Hint: the area between the two values is 0.9. Since they are symmetrical on either side of the mean, that leaves an area of 0.1 divided by 2 = 0.05 in the tails of the distribution.) ο οο 126.5 mm Hg, 149.5 mm Hg 116.9 mm Hg, 159.1 mm Hg 117.9 mm Hg, 160.1 mm Hg O.121.6 mm Hg, 154.4 mm Hg

Assume that the readings on the thermometers are normally distributed with a mean of 0° and standard deviation of 1.00°C. Assume 2.1% of the thermometers are rejected because they have readings that are too high and another 2.1% are rejected because they have readings that are too low. Draw a sketch and find the two readings that are cutoff values separating the rejected thermometers from the others.
