O 3/2 points I Previous Answers BBUnderStat10 93.005. Prehistoric pottery vessels are usually found as sherds (broken pieces) are carefully enough sherds can be found. An archaeological study and reconstructed if provides data relating x body diameter in centimeters and y height in centimeters of prehistoric vessels reconstructed from sherds found at a prehistoric site. The following Minitab printout provides an analysis of the data. Predictor SE Coef Constant 429 4.079 0 a) Minitab calls the explanatory variable the predictor variable which is the predictor variable, the diameter of the pot or the height? height O diameter (b) For the least-squares line a bx, what is the value of the constant a? What is the value of the slope D? (Note: The slope s the coemoent of the predictor variable.) the equation of the least-squares line. (c) The P-value for a two-tailed test corresponding to each coefficient is listed under P. The t value corresponding to coemoent is isted under T What the is the P-value of the slope? What are the hypotheses for a two-tailed test of o?Explanation / Answer
Solution:-
a) The predictor variable is diameter.
b) The regression equation is Y = - 0.254 + 0.8094*X.
a = - 0.254
b = 0.8094
Y = a + b*X
Y = - 0.254 + 0.8094*X
c) The p value of the slope is 0.08.
d)
State the hypotheses. The first step is to state the null hypothesis and an alternative hypothesis.
H0: The slope of the regression line is equal to zero.
Ha: The slope of the regression line is not equal to zero.
If the relationship between height and diameter is significant, the slope will not equal zero.
