The trick Is to break it up 2 hours and 20 minutes and convert the 20 minute into hours, so if he runs at 6km/h then in 2 hours he ran 12 kms and 20 minutes in hours = 1/3 of hour therefore 6 multiplied by 1/3 is 2 km therefore th total he ran was 14 kms

Answer:

(B) (0.396, 1.712)

Step-by-step explanation:

From the information given;

Confidence Interval = 0.95

Significance Level $= 1 - 0.95 = 0.05$

The confidence interval for regression coefficient beta (whereby in this case it is the coefficient of the diameter) is expressed by:

= $( Beta ^- \ t_{n-2}, \alpha/2 ( S.E \ of \ \^ \ \ ), Beta^+ \ t_{n-2}, \alpha/2 ( S.E \ of \ \^ \ \ ))$

From the regression coefficient, the estimated value of beta^ = 1.054

$= (1.054 - t_{29,0.025} *(0.322), 1.054 + t_{29,0.025}*(0.322))$

$t_{229,0.025} = 2.0452\\\\ = \mathbf{(0.396, 1.712)}$
