According to "Reproductive Blology of the Aquatic Salamander Amphiuma tridactylum in Louisiana,"+ the size of a female salamander's snout is correlated with the number of eggs in her clutch. The following data are consistent with summary quantities reported in the article Partial Minitab output is also included Snout-Vent Length Clutch Size 32 45 53 215 53 160 53 170 54 190 52 200 57 270 58 175 59 245 59 215 63 170 63 240 64 245 67 290 The regression equation is Y = -233 5.92 Dracotor Coas Stay T Constant -133.02 84.30 2.07 5.919 1.-27 5.25 - 33.0 - - 9.72 Rugiad - 67.22 Additional summary statistics are glven below. n = 14 x = 56.5 ✓ = 201.4 0.060 0.0002
- = 33.00 2-39 = 69.77 Rad = 67.27 Additional summary statistics are given below. - 14 X - 56.5 Ex2 = 45,597 Y2 - 613,550 y - 201.4 Exy - 164,690 You can use the Distribution Calculators page in SALI to find critical values and/or p-values to answer parts of this question. (a) What is the equation of the regression line for predicting clutch size based on snout-vent length (Let x - snout venit length and y-clutch size. Round your intercept to two decimal places and your slope lo three decimal places.) (b) What is the value of the estimated standard deviation of b2 (Round your answer to three decimal places.) () is there sufficient evidence to conclude that the slope of the population line is positive? No. Since the estimated slope is positive and since the P-value small we do not have convincing evidence that the slope of the population regression line is positive Yes. Since the estimated stope is positive and since the P-value is small we have convincing evidence that the slope of the population regression line is positive. Yes. Since the estimated slope is positive and since the P-value is large we have convincing evidence that the slope of the population regression line is positive. O No. Since the estimated slope is positive and since the P-value large we do not have convincing evidence that the slope of the population regression line is positive. (d) Predict the clutch size for a salamander with a snout-vent length of 50 using a 95% Interval. (Round your answers to three decimal places. It it is not appropriate to find a prediction interval, enter NA In both blanks.) (e) Predict the clutch size for a salamander with a snout-vent length of 115 using a 90% Interval. (Round your answers to three decimal places. Round your answers to three decimal places. Tt it is not appropriate to find a prediction interval, enter NA in both blanks.)
