These are the missing parts as well in addition to the picture. It could not all fit......D) Sketch graph E) Based on your answers in part (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at level a? multiple choice 1- At the a= 0.05 level, we will fail to reject the null hypothesis and conclude the data are not statistically significant. 2-At the a= 0.05 level, We reject the null hypothesis and conclude the data are not statistically significant. 3-At the a= 0.05 level, We will fail to reject the null hypothesis and conclude the data are statistically significant. 4- At the a= 0.05 level, We reject the null hypothesis and conclude the data are statistically significant.F) Interpret your conclusion in the context of the application. (Multiple choice) 1- Fail to reject the null hypothesis, there is sufficient evidence that the mean rate of hay fever is over for the age group over 50. 2- Reject the Null hypothesis, there is insufficient evidence that the mean rate of hayfever is lower for the age group over 50. 3- Reject the null hypothesis, there is sufficient evidence that the main rate of a fever is lower for the age group over 50. 4-Fail to reject the null hypothesis, there is insufficient evidence that the main rate of a fever is lower for the age group over 50.

13. [-/4.17 Points] DETAILS BBUNDERSTAT12 8.5.020.5. MY NOTES ASK YOUR TEACHER A random sample of n, = 16 communities in western Kansas gave the following information for people under 25 years of age. x1: Rate of hay fever per 1000 population for people under 25 7 92 119 126 91 123 112 93 125 95 125 117 97 122 127 88 A random sample of n2 = 14 regions in western Kansas gave the following information for people over 50 years old. X2: Rate of hay fever per 1000 population for people over 50 93 109 99 95 110 88 110 79 115 100 89 114 85 96 LA USE SALT (1) Use a calculator to calculate x1, $1, X2, and $2. (Round your answers to four decimal places.) X1 = a) What is the level of significance? il) Assume that the hay fever rate in each age group has an approximately normal distribution. Do the data indicate that the age group over 50 has a lower rate of hay fever? Use a = 0.05. State the null and alternate hypotheses. Ho: #1 = #2; H1: H1 * H2 HO: #1 > #2; H1: H1 = H2 Ho: #1 = #2; H1: H1 > H2 Ho: #1 = #2; H1: H1 0.250 0.125
