Researchers Examined Hormonal Changes in 39 Women During the Menopausal

Question 24

Multiple Choice

Researchers examined hormonal changes in 39 women during the menopausal years. They found a weak linear relationship between age (in years) and the six-month percent change in plasma level of the reproductive hormone LH (luteinizing hormone) . Software gives the following output for a least-squares regression analysis:

 Predictor  Coef  SE Coef TP Constant 101.4679.051.280.207 age 1.6271.5591.040.303\begin{array} { l r r r r } \text { Predictor } & \text { Coef } & \text { SE Coef } & \mathrm { T } & \mathrm { P } \\\text { Constant } & 101.46 & 79.05 & 1.28 & 0.207 \\\text { age } & - 1.627 & 1.559 & - 1.04 & 0.303\end{array}
S = 41.5236 R-Sq = 2.9% R-Sq(adj) = 0.2%
Using a significance level of 0.05, which of the following conclusions best describes the findings?


A) The study failed to find evidence (P > 0.05) of a linear relationship between age and the six-month percent change in LH during the menopausal years.
B) The study failed to find evidence (P < 0.05) of a linear relationship between age and the six-month percent change in LH during the menopausal years.
C) The study found significant evidence (P > 0.05) of a linear relationship between age and the six-month percent change in LH during the menopausal years.
D) The study found significant evidence (P < 0.05) of a linear relationship between age and the six-month percent change in LH during the menopausal years.
