for the diee e1 Find 2. According to an article in the San Gabriel Valley Tribune (2-13-03), \"Most people are kissing the \'right way.\" That is, according to the study, the majority of couples tilt their kissing the \'right way That is, according to the study, the majority of couples ilit their heads to the right when kissing. In the study, a researcher observed 124 couples kissing in various public places and found that 83/l 24 (66.9%) of the couples tilted to the right. Is this convincing evidence that proportion of those who \"kiss right\" p > .5?

Solution

2. Null hypothesis: P=0.5

Alternative hypothesis: P>0.5

Yes. The P>0.5 is a convincing evidence since P-value is very less

3)

No. population mean life span for honololu is not less than 77 years

1)

Null hypothsis: The average life is 30

Alternative hypothesis: The average life of batteries is more than average 30

Since the average 30 lies in the lower and upper intervals (28.47,39.33) we accept the null hypothesis.

Hence we conclud that the average life not last longer than the average.

b) 95% confidence interval is (28.47, 39.33)
