There are two main fishing spots in a certain video game, a river and a lake. In the river, out of the 57 fish that were caught, 31 of them were trout. In the lake, out of the 64 fish that were caught, 24 of them were trout. Use a significance level of a = 0.02 to test the claim that the proportion of trout in the river is greater than the proportion of trout in the lake. Let the river represent population 1, and the lake represent population 2. a.) State the null and alternative hypothesis using correct symbolic form. Ho: P1 P2 H1: P1 + P2 b.) What is the critical value? (round to two decimal places)
I am only given one attempt at this. I need help. A newspaper report conducted a survey of 753 people in New York City and found that 27% of the population believe that the Yankees will miss the playoffs this year.

The Consumer Reports Restaurant Customer Satisfaction Survey is based upon 148,599 visits to full-service restaurant chains.t One of the variables in the study is meal price, the average amount paid per person for dinner and drinks, minus the tip. Suppose a reporter for the Sun Coast times thought that it would be of interest to her readers to conduct a similar study for restaurants located on the Grand Strand section in Myrtle Beach, South Carolina. The reporter selected a sample of 8 seafood restaurants, 8 Italian restaurants, and 8 steakhouses. The following data show the meal prices ($) obtained for the 24 restaurants sampled. Italian Seafood Steakhouse $12 $16 $24 13 18 19 15 17 23 17 26 25 18 23 21 20 15 22 17 19 27 24 18 31 Use a = 0.05 to test whether there is a significant difference among the mean meal price for the three types of restaurants.

As a prospective teacher, communication skills occupy a very important position, because communication skills will affect the understanding of the students they teach. With good communication skills, a teacher can convey his ideas or ideas well, on the other hand, if his communication skills are not good, the ideas or ideas will not be conveyed perfectly. Communication skills provide opportunities for students to convey their ideas both verbally and in writing and learn to respect the opinions of others. Communication is a process of giving and conveying meaning in an effort to create mutual understanding. Communication is a process, not a static thing, so communication. Students from well-known universities in Jakarta are students who are prepared to become prospective teachers in elementary schools. Thus, these students need to be prepared and trained from an early age to develop communication skills. This is because to form students with good communication skills requires a long…

Kentville, a community of 10,000 people, resides next to a krypton mine, and there is a concern that the emission from the krypton smelter have resulted in adverse effects. Specifically, Kryptonosis seems to have killed 12 of Kentville’s inhabitants last year. A neighboring community, Lanesburg, has 25,000 inhabitants and is far enough from the smelter to not be affected by the emission. In Lanesburg, only three people last year died of Kryptonosis. Given that the number of deaths in Kentville and their causes last year were: Heart attack=7 Accidents=4 Kryptonosis=12 Other=6 What is the risk of dying of Kryptonosis in Kentville relative to non-contaminated locality?What is the risk of dying of Kryptonosis in Kentville relative to deaths due to other causes? How many times the chance of dying of Kryptonosis compared to dying of accidents ? How many times the chance of dying of Kryptonosis compared to Other causes?
A local company is interested in supporting environmentally friendly initiatives such as carpooling among employees. The company surveyed all of the 200 employees at the downtown offices. Employees responded as to whether or not they own a car and to the location of the home where they live. The results are shown in the table below. If the person owns a car, he or she is more likely to live elsewhere in the city than to live in the downtown area in the city. If the person does not own a car, he or she is more likely to live outside the city than to live in the city (downtown area or elsewhere). The person is more likely to own a car if he or she lives in the city (downtown area or elsewhere) than if he or she lives outside the city. The person is more likely to live in the downtown area in the city than elsewhere in the city. The person is more likely to own a car than not to own a car.
Seven percent of those who invest in mutual funds consider corporate stocks to be “very safe”, 58% consider them “relatively safe”, 24% consider them “not very safe”, 4% consider them “not safe” and 7% "They are not safe at all." Business / Week / Harris asked 550 mutual fund investors how they would rate corporate bonds for safety. The answers were the following Seguridad Frecuencia Very safe 62 Relatively safe 323 Not very safe 76 Not safe 26 Not safe at all 63 Does the attitude of mutual fund investors differ from corporate bonds from their attitude to corporate stocks? Support your conclusion by giving a statistical test. Use α = 0.01. For this problem you must present: -Hypothesis-Result of the expected values, residuals and the calculation of the test statistic.-Analysis of the results in the chi square test and its conclusion in applied terms of the problem
