How to find extreme values? 1) P(z<z*)=0.05 2) P(z>z*)=0.025 3) find the "most extreme 5%" by separating it from the middle 95%.
b-2. Find the p-value. 0.01 s p-value< 0.025 0.025 p-value < 0.05 0.05 s p-value < 0.10 p-value 010 p-value O.01 b-3. At the 0.10 significance level, What is the conclusion? Reject Ho since the p-value is greater than significance level. Reject Ho since the p-value is smaller than significance level. Do not reject Ho since the p-value is greater than significance level. Do not reject Ho since the p-value is smaller than significance level. b-4. Interpret the results at...
looking for an explanation as to why are all populations are not equal and how to find the p-value on the chart/excel, Thank you ahead of time. Consider the following sample information: k=5 and H= 12.9. Use Table 3: a. Specify the competing hypotheses to test whether some differences exist between the medians. He: m1 = m2 = m3 = m4 = ms; HA: Not all population medians are equal. Ho: m = m = m3 = mA = m5;...
Consider the equation log(unemployed) = 0.284 - 0.025*spending + 0.0045 * int_rate. By how much (EXACTLY) does unemployed decrease when spending increases by 2? (a) 5.1%. (b) 5.2% (c) 0.052%. (d) 0.051%.
Use the z-table to find the following probabilities. A.) P( z<-1) B.) P(z is greater than or equal to 2.25) C.) P(-1<z<2.25)
How to write this formula in Excel? = 2P(Z > 1 = 2P(Z > 2.95 P -value 2P(Z> 2.95) = 2[1-P(Z < 2.95)]
or each of the following situations, find the critical value(s) for z. a) Ho: p=0.09 vs. Ha:p>0.09 at a = 0.05. b) He: p=0.5 vs. Ha:p*0.5 at a = 0.05. 5) Ho: p=0.8 vs. Ha:p<0.8 at a = 0.025; n = 304. :) Ho: p=0.3 vs. Ha: p<0.3 at a = 0.025. 3) The critical value(s) is (are) z* = 1.64 Round to two decimal places as needed. Use a comma to separate answers as needed.) b) The critical value(s)...
