The data given were collected to determine whether the life span of randomly selected mammals, in years, can be predicted from their corresponding gestation periods.
Gestation 8 2.1 1.3 1 11.5 5.3 3.8 24.3
Life span 30 13 8 4 28 11 12 42
Identify the explanatory variable
A. Climate
B. Life span
C. months
D. gestation
E. mammal breed
Ans:
We are given two variables gestation period and life span.
As,we are interested to determine whether the life span of randomly selected mammals, in years, can be predicted from their corresponding gestation periods.
So,gestation period is perdictor or explanatory variable and life span is response variable.
So,correct answer will be D( gestation period).
The data given were collected to determine whether the life span of randomly selected mammals, in...
4) The data below are the gestation periods, in months, of randomly selected animals and their corresponding life spans, in years. Calculate the correlation coefficient r. Gestation, x 8 2.1 1.3 1 11.5 5.3 3.8 24.3 Life span, y 30 12 6 3 25 12 10 40 5) Which of the following values could not represent a correlation coefficient? A) 0 B) 1.032 C) -1 D) 0.927

(1 point) In the following questions, use the normal distribution to find a confidence interval for a difference in proportions pu - P2 given the relevant sample results. Give the best point estimate for p. - P2, the margin of error, and the confidence interval. Assume the results come from random samples. Give your answers to 4 decimal places. 300. Use 1. A 80% interval for pı - P2 given that...
