Rainfall and corn crop yield reported for the 38 years from 1890 through 1927 give us thescatterplot shown below with an r = 0.0426. Yield is the number of ears of corn measured inmetric tons per hectare, rainfall is in inches.B. O45C. O40D. O35€30252015S7911Crop YieldRainBased on corn crop yield from Ezekiel, M. and K. A. Fox. (1959). Methods of Correlation and Regression Analysis.Wiley: New York.H: Crop yield is related to rainfall.H: Crop yield is not related to rainfall.13The plot shows a positive linear relationship between the inches of rainfall and the size of the corn yield.Based on the scatterplot and the value of the correlation coefficient, it would make sense to test the significance of thisobserved linear relationship between crop yield and rainfall.Which of the following are the appropriate null and alternative hypotheses?A. OH: Crop yield is not related to rainfall.H: Crop yield is related to rainfall.15H: Crop yield is not linearly related to rainfall.H: Crop yield is linearly related to rainfall.17H: Crop yield is linearly related to rainfall.H: Crop yield is not linearly related to rainfall.19

-Find the correct null hypothesis and for each correct alternative hypothesis 7. Suppose you hear a claim that the average score on a national exam is 78. You think the average is higher than that, and your sample of 100 students produces an average of 75. What are the null and alternative hypotheses?
researcher would like to examine the effect of fertilizer on flower growth. She obtains several flowers. She randomly assigns half the plants to the no fertilizer condition. The other half of the plants receive fertilizer. She monitors their growth for a month. She then compares the amount of growth of the two sets of plants. Is there a difference in growth between the no fertilizer and the fertilizer conditions? Use the .05 level of significance. In addition, find Cohen’s d and state what the effect size is in a sentence. Growth Rating No Fertilizer 40,21,27,30, 47 Fertilizer 46,25, 24, 38, 53
According to a New York Times/CBS News poll conducted during June 24–28, 2011, 55% of the American adults polled said that owning a home is a very important part of the American Dream (The New York Times, June 30, 2011). Suppose this result was true for the population of all American adults in 2011. In a recent poll of 1780 American adults, 60% said that owning a home is a very important part of the American Dream. Perform a hypothesis test to determine whether it is reasonable to conclude that the percentage of all American adults who currently hold this opinion is higher than 55%. Use a 10% significance level, and use both the p-value and the critical-value approaches. Round your answers for the observed value of z and the critical value of z to two decimal places, and the p-value to four decimal places.zobserved =Enter you answer; z_observed p-value =Enter you answer; p-value Critical value =Enter you answer; Critical value

In a recent Super Bowl, a TV network predicted that 25 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 138 people who saw the commercials and found that 42 of them said they would watch one of the television shows.

You may need to use the appropriate appendix table or technology to answer this question. In 2012, seventy percent of Canadian households had an internet connection. A sample of 370 households taken in 2013 showed that 76% of them had an internet connection. We are interested in determining whether or not there has been a significant increase in the percentage of the Canadian households that have internet connections. (a) State the null and alternative hypotheses to be tested. (Enter != for as needed. Let p be the proportion of all Canadian households with internet connections.) Ho: на: (b) Compute the test statistic. (Round your answer to two decimal places.) (c) The null hypothesis is to be tested at the 5% level of significance. Determine the critical value(s) for this test. (Round your answer(s) to two decimal places. If the test is one-tailed, enter NONE for the unused tail.) test statistic (d) What do you conclude? Do not reject Ho. We can conclude that there has been a…
