A researcher expects a treatment to produce an increase in the population mean. The treatment is evaluated using a one tailed hypothesis test, and the test produces z =-1.85. Based on this result, what is the correct statistical decision?O The researcher should reject the null hypothesis with either a = .05 or α = .01.O The researcher should reject the null hypothesis with a = .05 but not with α = .01.O cannot answer without additional informationO The researcher should fail to reject Ho with either a = .05 or α = .01.

Solution-: Given: ZStat=-1.85 (one tailed hypothesis) We want to find based on this result, what is…

Before the semester began, Professor Keithley predicted that 15% of hisphilosophy students would receive an A, 30% a B, 40% a C, 10% a D, and 5%an F. At the end of the semester, 14 of Professor Keithley’s philosophy studentsearned an A, 19 a B, 12 a C, 5 a D, and 2 an F.Use the Chi-Square test and a 0.05 level of significance to determine if ProfessorKeithley’s predicted percentages were accurate. (State your null and alternativehypothesis, find the critical values and test statistics, make a decision, and writea conclusion based on your results).
