Real Fruit Snacks” there were five Bam-Bam snack pieces. The total number of snack pieces in the six bags was 68. We wish to calculate a 96% confidence interval for the population proportion of Bam-Bam snack pieces. Construct a 96% confidence interval for the population proportion of Bam-Bam snack pieces per bag and calculate the error bound. Do you think that six packages of fruit snacks yield enough data to give accurate results? Why or why not?

In a recent poll, 134 registered voters who planned to vote in the next election were asked if they would vote for a particular candidate and 80 of these people responded that they would. We wish to predict the proportion of people who will vote for this candidate in the election. a) Find a point estimator of the proportion who would vote for this candidate. b) Construct a 90% confidence interval for the true proportion who would vote for this...

Suppose that insurance companies did a survey. They randomly surveyed 450 drivers and found that 340 claimed they always buckle up. We are interested in the population proportion of drivers who claim they always buckle up. NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) A. (i) Enter an exact number as an integer, fraction, or decimal. x = (ii) Enter an...

i. A researcher estimated the proportion of voters who favor the Democratic candidate in an election. Based on 500 people she calculates the 95% confidence interval for the population proportion p:   0.123 <p<0.181. Which of the following is a valid interpretation of this confidence interval ?______ a. There is a 95% chance that the true value of p lies between 0.123 and 0.181 b.   If many different samples of 500 were selected and a confidence interval was constructed based on...

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 43 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that σ = 7.70 ml/kg for the distribution of blood plasma. (b) What conditions...

A debate rages whether or not bottled water is worth the cost. The National Resource Defense Council concludes, “there is no assurance that bottled water it is any cleaner or safer than tap (water).” But, in addition to the safety issue, many people prefer the taste of bottled water to tap water, or so they say! Let’s suppose that the city council members of Corvallis are trying to show that the city of Corvallis tap water tastes just as good...

BridgeRock is a major manufacturer of tires in the U.S.. The company had five manufacturing facilities where tires were made and another 20 facilities for various components and materials used in tires. Each manufacturing facility produced 10,000 tires every hour. Quality had always been emphasized at BridgeRock, but lately quality was a bigger issue because of recent fatal accidents involving tires made by other manufacturers due to tread separation. All tire manufacturers were under pressure to ensure problems did not...
