On numerous studies, it was found that a well-cared cat can live beyond 15 years. Eriel, a cat-lover, wants to verify this fact in her community. Hence, she took a random sample of 25 cat owners and ask them of the age during the time their pet cat died. She found a mean life span of 15.7 years with a standard deviation of 1.9 years. She run some analysis in R to help her verify this fact at 5% level of significance. Shapiro-Wilk normality test data: lifespan W = 0.94224, p-value = 0.1830 One Sample t-test data: lifespan t= 1.8421, df = 24, p-value = 0.0389 The appropriate null and alternative hypotheses to verify the claim is ___________. Ho: Ha:

Shapiro-Wilk normality test
data: lifespan
W = 0.94224, p-value = 0.1830
One Sample t-test
data: lifespan
t= 1.8421, df = 24, p-value = 0.0389
The appropriate null and alternative hypotheses to verify the claim is ___________.
Ho:
Ha:
Step by step
Solved in 2 steps
1. True or False: The normality assumption was satisfied at 5% level of significance.
2. True or False: To answer Eriel’s objective, one-sample t-test is the appropriate procedure to use.
3. True or False: The decision is to reject Ho.
4: True or False: There is no sufficient evidence to say that the average lifespan of cats is beyond 15 years.
