Since you have asked multiple questions, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question. The difference is, Treatment 1 Treatment 2 Difference 21 18 3 28 30 -2 30 25 5 26 22 4 29 21 8 The mean for difference between treatment 1 and treatment 2 is, x¯d=∑iXdn=3-2+5+4+85=185=3.6 The mean for difference between treatment 1 and treatment 2 is 3.6. The standard deviation for difference between treatment 1 and treatment 2 is, sd=∑iXd-x¯d2n-1=3-3.62+-2-3.62+5-3.62+4-3.62+8-3.615-1=53.24=13.3=3.6469 The standard deviation for difference between treatment 1 and treatment 2 is 3.6469.The best point estimate is, Point estimate=x¯d=3.6 Thus, the best point estimate is 3.6. The degrees of freedom is, df=n-1=5-1=4 The degrees of freedom is 4. The confidence level is 99%, than the level of significance is 0.01. Computation of critical value: The critical value of t-distribution for 0.01 level of significance at 4 degrees of freedom can be obtained using the excel formula “=T.INV.2T(0.01,4)”. The critical value is 4.6041. The margin of error is, E=tα2sdn=4.60413.64695=7.5090≈7.51 Thus, the margin of error is 7.51. The 99% confidence interval is, CI=x¯d±E=3.6±7.51=3.6-7.51,3.6+7.51=-3.91,11.11 Thus, the 99% confidence interval is -3.91 to 11.11.

One method for measuring air pollution is to measure the concentration of carbon monoxide, or CO, in the air. Suppose Nina, an environmental scientist, wishes to estimate the CO concentration in Zagreb, Croatia. She randomly selects 45 locations throughout the city measures the CO concentration at each location. Based on her 45 samples, she computes the margin of error for a 95% t-confidence interval for the mean concentration of CO in Zagreb, in µg/m³, to be 4.28. What would happen to the margin of error if Nina decreases the confidence level to 90%? Nina increases the confidence level to 99%? Nina decreases the sample size to 33 locations? Nina increases the sample size to 65 locations? Answer Bank Increase Stay the same Decrease
