A quality-conscious disk manufacturer wishes to know the fraction of disks his company makes which are defective. Step 1 of 2: Suppose a sample of 1875 floppy disks is drawn. Of these disks, 1594 were not defective. Using the data, estimate the proportion of disks which are defective. Enter your answer as a fraction or a decimal number rounded to three decimal places.

The control department of a light bulb manufacturer randomly picks 4400 light bulbs from the production lot every week. The records show that, when there is no malfunction, the defect rate in the manufacturing process (due to imperfections in the material used) is 1% . When 1.5% or more of the light bulbs in the sample of 4400 are defective, the control unit calls repair technicians for service. Answer the following. (If necessary, consult a list of formulas.) (a)Find the mean of p , where p is the proportion of defective light bulbs in a sample of 4400 when there is no malfunction. (b)Find the standard deviation of p . (c)Compute an approximation for P≥p0.015 , which is the probability that the service technicians will be called even though the system is functioning properly. Round your answer to four decimal places.
The state population is recorded as 1,200,000. There were 60,250 total deaths for the year. There were 615 confirmed cases of Hepatitis A were reported to the state health department of which 30 died. What was the cause-specific death rate for the year? Hint: Take the case specific deaths divided into the total state population. Make sure to include the % sign.
A researcher wants to determine the percentage of American teenagers who send or receive text messages while doing homework. Which of the following techniques would likely be the MOST efficient way of obtaining an accurate estimate for this percentage? 1. Randomly select teenagers from the list of all teenage students in every state in America and mail surveys to those teens, asking them if they send or receive text messages while doing homework. 2. Send a survey to every teenager in America and ask them if they send or receive text messages while doing homework. 3. Randomly select teenagers from the list of all teenage students in one state and mail surveys to those teens, asking them if they send or receive text messages while doing homework.
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.

A sample of 10 male students was taken from the population of SHS male students in JRU. The heights (in inches) of those 10 students are as follows: 60, 72, 70, 68, 70, 62, 66, 64, 66, 56. What is the point estimate for the average height of all SHS male students in JRU?
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…
