2. 3 Arterial pressure #1 #2 Patient Nurse Nurse 1 117 120 105 110 108 110 4 94 98 5 140 138 6 165 170 7 132 130 8 143 150 9 98 105 10 112 117 11 109 110

Answer 1

classmate Date Page Nariantes a) 7 t- Test Two sample. Assuming Equal Null hypothecais: Mean of Blood Pressure taken Nurse and Nurse #2 are equal by Alternative Mean of Nurse 7 and bypothesis Blood Pressure taken by Nurse #2 ate not equal 2 t- Test: Paired Two s Paired Two gample for Moon Nu hupathesis Hean of blood pressure taken by Nurse # 1 and Nurse #2 are equal. Alternative hypothesis. Mean of Blood Presgute taken by Nurse and Nurse # 2 are not equal. 1 1 by ?) P-value is 0.7360 4 776 so that ✓ By t- Test: Two Sample assuming equal variances which is less than significance level o-os. we ngert Accept out hoppothesis and say Mean Blood Pressure taken by Nurse I and Nurse #2 are equal. Test: Paired two sample for theans 0.00 74 502 which is greater than 0.06 Hence, here we a regent hull hypothesis, ie e By + P-value is,

classmate Date Page are not Hence we conclude that Blood presure measured by Nurse # 1 and Nurse # 2 equal 9 Reasearcherg ie Investigater 2 camed out the analysis Because, Experiment is camied out same patient by two different Nurse and which is case usual ally solved by paised t-test: Paired Two Sample for means
