- Based on information from a large insurance company, 66% of all damage liability claims are made by single people under the age of 25. A random sample of 54 claims showed that 41 were made by single people under the age of 25. Does this indicate that the insurance claims of single people under the age of 25 is higher than the national percent reported by the large insurance company? State the null and alternate hypothesis. a) Ho: p = .66, Ha: p ≠ .66 b) Ho: p = .66, Ha: p > .66 c) Ho: p = .76, Ha: p < .76 d) Ho: p = .76, Ha: p > .76 e) Ho: p = .66, Ha: p < .66According to Facebook's self-reported statistics, the average Facebook user has 130 Facebook friends. For a statistics project a student at Contra Costa College tests the hypothesis that CCC students will average more than 130 Facebook friends. She randomly selects 3 classes from the schedule of classes and distributes a survey in these classes. Her sample contains 45 students. Here are the null and alternative hypotheses for her study: H: μ = 130, H: μ> 130. What does μ represent in these hypotheses? A. O Mean number of Facebook friends for the average user B. Mean number of Facebook friends for CCC students C. O Mean number of Facebook friends for the CCC students in her sampleSuppose that one chemical plant in a large corporation is accused of exceeding the established limits of toxins being released into the atmosphere. A decision is made to test whether or not the mean level of toxins exceeds the tolerance level μ0=100μ0=100 ppm (parts per million). How would the null and alternative hypotheses be set up given that the researcher is working for the corporation? How would those hypotheses change if the researcher is working for the Environmental Protection Agency (EPA)?
- Suppose a business person wishes to open a store in a local shopping centre only if there is strong evidence that the average number of people in the centre is greater than 5000 per day. What is the null hypothesis will be: H0: μ < 5000 or H0: μ > 5000 or H0: μ ≤ 5000 or H0: μ ≥ 5000The population of healthy female adults, the mean red blood cell count (RBC) is 4.8 (millions of cells per cubic millimeter of whole blood). A researcher thinks the RBC is underestimated, so she conducts a test of significance using Null Hypothesis: µ ≤ 4.8 vs. Alternative Hypothesis: µ >4.8. If the true mean RBC is 4.75 and the null hypothesis is rejected, out of the four options below, what has occured? Type 1 Error, Type 2 Error, No error, OR can’t tell without knowing the degrees of freedom?1. Identify the parameter and set up null and alternative hypotheses. A drug company says their brand of over the counter pain medicine contains on average 1.25 grams of acetaminophen in each tablet. A consumer wants to find evidence against the drug company's claim. 1. Identify the parameter: 2. Null hypothesis: 3. Alternative Hypothesis: а. b. Social scientists suspects the median age of women at the birth of the first child is more than 25 years. 1. Identify the parameter: 2. Null hypothesis 3. Alernative Hypothesis: c. A consumer advocacy group wants to prove there is no difference between regular unleaded and premium unleaded average gas mileage. 1.

- 1. Formulate the null and the alternative hypothesis. a) A city had an unemployment rate of 7%. The mayor pledged to lower this figure and supported programs to decrease unemployment. A group of citizens wanted to test if the unemployment rate had actually decreased, so they obtained a random sample of citizens to see what proportion of the sample was unemployed. b) A restaurant owner installed a new automated drink machine. The machine is designed to dispense 530 mL of liquid on the medium size setting. The owner suspects that the machine may be dispensing too much in medium drinks. They decide to take a sample of 30 medium drinks to see the average amount is significantly greater than 530 mL.A sample of 60 chewable vitamin tablets have a sample mean of 298 milligrams of vitamin C. Nutritionists want to perform a hypothesis test to determine how strong the evidence is that the mean mass of vitamin C per tablet differs from 299 milligrams. State the appropriate null and alternate hypotheses.16. According to a food website, the mean consumption of popcorn annually by Americans division of the food website unleashes an aggressive campaign designed to get Americans to consume even more popcorn. Complete parts (a) through (c) below. 63 quarts. The marketing (a) Determine the null and alternative hypotheses that would be used to test the effectiveness of the marketing campaign. (1) (2) Ho: (3) (4) H1: (Type integers or decimals. Do not round.) (b) A sample of 895 Americans provides enough evidence to conclude that marketing campaign was effective. Provide a statement that should be put out by the marketing department. O A. There is not sufficient evidence to conclude that the mean consumption of popcorn has stayed the same. O B. There is not sufficient evidence to conclude that the mean consumption of popcorn has risen. O C. There is sufficient evidence to conclude that the mean consumption of popcorn has stayed the same.

- Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 37 passengers, and a flight has fuel and baggage that allows for a total passenger load of 5,994lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 5,994/37lb=162lb. What is the probability that the aircraft is overloaded? Should the pilot take any action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 181.6lb and a standard deviation of 36.2. The probability is approximately?Suppose you want to test the claim that a population mean equals 40. (a) State the null hypothesis. H0: μ > 40 H0: μ < 40 H0: μ = 40 H0: μ ≠ 40 H0: μ ≥ 40 (b) State the alternate hypothesis if you have no information regarding how the population mean might differ from 40. H1: μ > 40 H1: μ < 40 H1: μ = 40 H1: μ ≠ 40 H1: μ ≥ 40 (c) State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may exceed 40. H1: μ > 40 H1: μ < 40 H1: μ = 40 H1: μ ≠ 40 H1: μ ≥ 40How would a person set up the hypotheses if they wanted to test the claim: the mean temperature of a October day in Oahu is different from 81 degrees? A: Ho µ = 81° vs HA H > 81° B: Ho H = 81° vs HA H 81° A
