Please help me to answer these 4 MCQs Thank u

Assume you have m independent samples having the same sample size. lfthe variance for the first sample is 50 and the variance for the second sample is 40, men me pooled variance for these Mo samples is 45. m \\2 A I I \\_( False Consider the following partially completed one-way ANOVA summary table: Source Degrees of freedom Sum of squares Mean sum of squares F Between groups 50 Within groups 20 Total 22 150 Based on this information, the p-value for the test statistic is Oa. between 2.5% and 5% Ob. between 1% and 2.5% OC above 10% Od. between 5% and 10% QUESTION 17 The expected value of perfect information (EVPI) indicates an upper limit on the amount a decision-maker should be willing to spend to obtain additional information. True OFalseAn economics professor believes that debt payments are influenced by income and the unemployment rate. She collects data on debt payments (in $), income (in $1,000s), and unemployment rate (in %) from 26 metropolitan areas and obtains the following regression results: Coefficients Standard error Intercept 199 156.36 Income 10.51 1.48 Unemployment rate 0.62 6.87 Based on this information, the regression coefficient on income can be interpreted as follows. a. If income increases by $1,000, then mean debt payments are estimated to increase by $209.51, holding the unemployment rate constant. Ob. If income increases by $1,000, then mean debt payments are estimated to increase by $10.51, holding the unemployment rate constant. C. If income increases by $10.51, then mean debt payments are estimated to increase by $0.62, holding the unemployment rate constant. Od. If income increases by $0.62, then mean debt payments are estimated to increase by $10.51, holding the unemployment rate constant
