Country A	Country B
314	303
339	322
328	317
302	331

Conduct an ANOVA test at a 0.05 level of significance to determine if there is any difference between the means.

Answer 1

There only two groups and we want to check the efficacy of treatment for COVID - 19in two different countries.

This problem can be solved by Minitab

The output is following

Data Entering :

Analysis :

Ho : both country have same efficacy for treatment COVID -19

H1:both country A and country B do not have same efficacy treatment COVID -19

For given analysis, p- value for ANOVA is 0.810

Decision : we accept Ho,because p- value is greater than = 0.05

Conclusion : there is insufficient statistical information to prove both country have different efficacy of treatment COVID-19 for country A and country B with level of significance = 0.05

Thank You!
