Microhabitat factors associated with forage and bed sites of barking deer in Hainan Island, China wereexamined from 2001 to 2002. In this region, woods make up 4.8% of the land, cultivated grass plot makes up14.7%, and deciduous forests makes up 39.6%. Of the 426 sites where the deer forage, 4 were categorized aswoods, 16 as cultivated grassplot, and 61 as deciduous forests. The table below summarizes these data.WoodsCultivated grassplot Deciduous forests OtherTotal41661345426a) Write the hypotheses for testing if barking deer prefer to forage in certain habitats over others.Ho: All habitats are equally prefered vs HA: Cultivated grassplot habitats are prefered over othersHo: All habitats are equally prefered vs HA: Wood habitats are prefered over othersHọ : All habitats are equally prefered vs HA: Some habitats are prefered over othersHo: All habitats are equally prefered vs HA: Deciduous habitats are prefered over othersb) What type of test can we use to answer this research question?O Chi-squareHypothesis test of meansHypothesis test of proportionsc) Do these data provide convincing evidence that barking deer prefer to forage in certain habitats overothers?

Solid fats are more likely to raise blood cholesterol levels than liquid fats. Suppose a nutritionist analyzed the percentage of saturated fat for a sample of 6 brands of stick margarine (solid fat) and for a sample of 6 brands of liquid margarine and obtained the following results: Stick:[25.5,26.7,26.5,26.6,26.3,26.4] Liquid:[16.5,17.1,17.5,17.3,17.2,16.7] We want to determine if there a significant difference in the average amount of saturated fat in solid and liquid fats. What is the test statistic? a) z = 39.604 b) t = 25.263 c) t = 39.604 d) z = 39.104 e) t = 39.104

Dr. Guidry conducts a study examining the relationship between the number of friends one has and the experience of daily stress and life satisfaction. She randomly samples 1,500 elderly men and women in Nashville, Tennessee (the state capital), located in the southern United States. Below are her findings.• Life satisfaction and experience of daily stress: r = .57 (p = .01)• Number of friends one has and experience of daily stress: r = .09, not sig.• Number of friends one has and life satisfaction: r = .36 (p = .04) Which of the following conclusions can Dr. Guidry draw about the number of friends one has and life satisfaction based on her statistical analyses? a. The probability of her sample coming from a zero association population is about 4%. (correct answer) b. The probability of her sample coming from a zero association population is about 96%. c. The relationship is not statistically significant. d. The strong correlation means that the number of friends one has causes an…

4. 0 There is some indication that as countries' levels of literacy increases, authoritarian tendencies decline among the population. The following data show literacy (measured in number of literate people per 10 people) and authoritarian scores on a standard authoritarinaism- measuring scale from 8 countries. The data are: Xiiteracy : 9.2, 7.5, 8.8, 6.5, 4.3, 5.9, 9.7, 8.5 XAuth: 2.1, 3.4, 2.5, 7.3, 8.9, 5.7, 1.3, 2.5 Is there a reliable relationship between the two variables? If yes, what would the predicted authoritarian score of a country where only quarter of the country is literate? What about for a country where the literacy rate is %100? Use alpha = .05.
7.05 In an experiment at Virginia Tech, 20 northern oak seedlings were exposed to a fungus. Half of the seedlings received 368 ppm of nitrogen (treatment) during planting, and the other half received no nitrogen (control). The stem weights in grams, at the end of 140 days were recorded as follows: Treat ment | .32 .53 .28 .37 .47 .43 .36 .42 .38 .43 Control .26 .43 .47 .49 .52 .75 .79 .86 .62 .46 Construct a 95% confidence interval for the difference in the mean stem weights between the treatment and control groups. Assume that the under- lying populations are normally distributed with equal variances.
An experiment was conducted to assess the efficacy of spraying oats with Malathion (at 0.25 lb/acre) to control the cereal leaf beetle. Twenty farms in southwest Manitoba were used for the study. Ten farms were assigned at random to the control group (no spray) and the other 10 fields were assigned to the treatment group (spray). At the conclusion of the experiment, the number of beetle larvae per square foot was measured at each farm, and a one-tailed test of significance was performed to determine if Malathion reduced the number of beetles. In which one of the following cases would a Type II error occur? (a) We do not conclude malathion is effective when in fact it was effective. (b) We conclude malathion is effective when in fact it is ineffective. (c) We conclude malathion is effective when in fact it is effective. (d) We do not conclude malathion is effective when in fact it is ineffective. (e) We conclude malathion is neither ineffective nor effective.
