Question 6 and 7

#6: At five weather stations on Trail Ridge Road in Rocky Mountain National Park, the peak wind gusts (in miles per hour) for January and April are recorded below. Weather Station 1 2 3 4 5 9 January 131 129 120 64 78 April PgUp 112 112 104 88 61 Does this information indicate that the peak wind gusts are higher in January than in April? Use a = 0.05. 6 Hypotheses: Sample test statistic: 3 Pgon Dele P-value = State your conclusion in the context of the application. # 7 : In environmental studies, sex ratios are of great importance. Wolf society, packs, and ecology have been studied extensively at different locations in the U.S. and foreign countries. Sex ratios for eight study sites in northern Europe are shown below. Location of Wolf Pack % Males (Winter) % Males (Summer) Finland 64 57 Finland 70 57 Finland 86 49 Lapland 55 48 Lapland 64 55 Russia 50 50 50 Russia 41 45 Russia 55 It is hypothesized that in winter, "loner" males (not present in summer packs) join the pack to increase survival rate. Use a 1% level of significance to test the claim that the average percentage of males in a wolf pack is higher in winter. S =13.17 d: 7, 13, 37; 7, 9, 0, -9, 10 d = 9.25 a. Hypotheses b. Sample test statistic: Sample test statistic: c. P-value = d. Based on your answers, will you reject or fail to reject the null hypothesis? e. Conclusion in the context of the application
