Null Hypothesis (HO<\/strong>): There is no significant difference in the average ratings between 4 mobile phones brands: Apple, Samsung, one plus, MI. All are the same.<\/p>\n

Alternate Hypothesis(H1):<\/strong> There is a significant difference in the average ratings between at least one pair of mobile phones brands Apple, Samsung, One plus, MI. One of them is different.<\/p>\n

According to Anova Table1 the P value is 0.1934 which is more than the significance value that is 0.05. This indicates we would accept null hypothesis and reject alternate hypothesis.<\/p>\n

Conclusion<\/strong>: As we accept null hypothesis and reject the alternate hypothesis This means that there is no significant difference in the average ratings between mobile phones brands, therefore all are same.<\/p>\n","protected":false},"excerpt":{"rendered":"
