Sample size Mean Median Standard deviation Longevity 40 13.5 12 7.245 Gestation a) Generate 2000 samples and find the 95% confidence interval for Longevity (click on two tail). Round to the nearest tenths. What does this interval indicate? Ho: Ha: 40 194.325 175.5 143.3888 The interval is from 152.2 to 239.7. This indicates what values the majority of data will fall in between. b) We are going to investigate if the mean in longevity differs from 10 years. What are the null and alternative hypotheses? 343 words c) Based on your confidence interval above, can we conclude if the mean in longevity differs from 10 years? Explain why or why not. Focus L
