The state education commission wants to estimate the fraction of tenth-grade students that have reading skills at or below the eighth-grade level. Step 1 of 2 : Suppose a sample of 1134 tenth graders is drawn. Of the students sampled, 226 read at or below the eighth-grade level. Using the data, estimate the proportion of tenth graders reading at or below the eighth-grade level. Enter your answer as a fraction or a decimal number rounded to three decimal places.
The NAEP music assessment scores for eighth grade students are approximately N (150, 35). Find the z-scores by standardizing the following scores: 150, 140, 100, 180, and 230. The percentile score is the proportion of students who would score LESS THAN OR EQUAL TO the score for the individual student. Compute the percentile scores for the five scores.
The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level. Suppose a sample of 2552 tenth graders is drawn. Of the students sampled, 2119 read above the eighth grade level. Using the data, estimate the proportion of tenth graders reading at or below the eighth grade level. Enter your answer as a fraction or a decimal number rounded to three decimal places.
The American Heart Association is about to conduct an anti-smoking campaign and wants to know the fraction of Americans over 35 who smoke. Step 1 of 2 : Suppose a sample of 1089 Americans over 35 is drawn. Of these people, 359 smoke. Using the data, estimate the proportion of Americans over 35 who smoke. Enter your answer as a fraction or a decimal number rounded to three decimal places.
As part of a sixth-grade class project the teacher brings to class a jar containing 200 gumballs of two different colors: red and green. Andy is asked to draw a sample of his own choosing and estimate the number of red gumballs in the jar. Andy draws a sample of 25 gumballs, of which 8 are red and 17 are green. Use Andy's sample to estimate the number of red gumballs in the jar. There are approximately Answer red gumballs in the jar.

The national profession exam for registered nurses, the NCLEX, has pass a rate of 85% for the first time exam takers. If 260 first time RN candidates were to take the exam, What is the mean for the number of people who pass?
The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level. Step 1 of 2: Suppose a sample of 333 tenth graders is drawn. Of the students sampled, 260 read above the eighth grade level. Using the data, estimate the proportion of tenth graders reading at or below the eighth grade level. Enter your answer as a fraction or a decimal number rounded to three decimal places. Step 2 of 2: Suppose a sample of 333 tenth graders is drawn. Of the students sampled, 260 read above the eighth grade level. Using the data, construct the 80% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level. Round your answers to three decimal places.
There are 435 seats in a nation's House of Representatives. The number of representatives per state is calculated using a statistical formula determined by law, but allocation is roughly proportionate to population. In 2010, the nation's population was estimated to be 309.1 million. The state's population was estimated at 26.1 million. How many representatives would you expect to be assigned to the state? Suppose the state actually has 34 representatives. Compare this with the expected number of representatives from the state.
The Sea Wharf Restaurant would like to determine the best way to allocate a monthly advertising budget of 55,000 between newspaper advertising and radio advertising. Management deidad that at least 30% of the budget must be spent on each type of media and that the amount of money spent on local newspaper advertising must be at least twice the amount spent on radia advertising. A marketing consultant developed an index that measures audience exposure per dollar of advertising on a scale from o to 100, with higher values implying greater audience exposure. If the velue of the index for local newspaper advertising is 80 end the value of the index for spot radio advertising is 90, how should the restaurant allocate its advertising budget to maximize the value of total audience exposure Formulate a inear programming model that can be used to determine how the restaurent should allocate its advertising budget in order to maximize the value of total audience exposure. (Assume Nis the amount…
