esc on Hurricane damage: In August and September 2005, Hurricanes Katrina and Rita caused extraordinary flooding in New Orleans, Louisiana. Many homes were severely damaged or destroyed, and of those that survived, many required extensive cleaning. It was thought that cleaning flood-damaged homes might present a health hazard due to the large amounts of mold present in many of the homes. In a sample of 355 residents of Orleans Parish who had participated in the cleaning of one or more homes, 75 had experienced symptoms of wheezing, and in a sample of 175 residents who had not participated in the cleaning, 25 reported wheezing symptoms (numbers read from a graph). Can you conclude that the proportion of residents with wheezing symptoms is greater among those who participated in the cleaning of flood-damaged homes? Let p, denote the proportion of residents with wheezing symptoms who had cleaned flood-damaged homes and p₂ denote the proportion of residents with wheezing symptoms who had not cleaned flood-damanged homes. Use the a=0.01 level of significance and the P-value method with the TI-84 Plus calculator. Part: 0/4 Part 1 of 4 State the null and alternate hypotheses.

H0​: The response of the subject and the gender of the subject are independent. H1​: The response of the subject and the gender of the subject are dependent.   B. H0​: The proportions of​ agree/disagree responses are different for the subjects interviewed by men and the subjects interviewed by women. H1​: The proportions are the same.   C.

A researcher wanted to determine if carpeted rooms contain more bacteria than uncarpeted rooms. The table shows the results for the number of bacteria per cubic foot for both types of rooms. Full data set O Carpeted Uncarpeted 9.4 9.1 16 10.8 6.4 10.8 14.8 8.8 11.5 11.6 13.7 9.4 10.7 12.4 13.4 7.8 Determine whether carpeted rooms have more bacteria than uncarpeted rooms at the a = 0.05 level of significance. Normal probability plots indicate that the data are approximately normal and boxplots indicate that there are no outliers. State the null and alternative hypotheses. Let population 1 be carpeted rooms and population 2 be uncarpeted rooms. OA Ho P1 H2 B. Ho H1 F2 OC Ho H= H2

An annual survey of first-year college students asks 277,000 students about their attitudes on a variety of subjects. According to a recent survey, 52% of first-year students believe that abortion should be legal. Use a 0.05 significanc level to test the claim that over half of all first-year students believe that abortion should be legal. Formulate the null and alternative hypotheses.

For each scenario below read the given null and alternative hypotheses statements as well as the initial decision about the null hypothesis. Post a conclusion about the claim in each test.   (This means when you post your answer, you do not need to include any statement about the null hypothesis. Only the final conclusion is needed.) **Chart 1 is attached** 1 Winning team data were collected for teams in different spots. use a .05 level of significance to test the claim that home/visitor wins are independent of the sport. **Table 1 is attached** P-Value=0.762

A hypothesis test is to be performed. Describe the two possible outcomes of the test using the context of the given situation.Last month the average waiting time at a bank was 8.4 minutes. The manager has installed a new computer system and claims that people will no longer have to wait as long. The hypotheses are as follows:Null hypothesis: average waiting time = 8.4 minutes  Alternative hypothesis: average waiting time < 8.4 minutes     Rejecting the null hypothesis means there is insufficient evidence that the mean waiting time is equal to 8.4 minutes. Accepting the null hypothesis means there is evidence to conclude that the mean waiting time is equal to 8.4 minutes.     Rejecting the null hypothesis means there is evidence that the mean waiting time is not equal to 8.4 minutes. Failing to reject the null hypothesis means there is insufficient evidence to conclude that the mean waiting time is less than 8.4 minutes.     Rejecting the null hypothesis means there is…
