Ten measurements of impact energy on specimens of a238 steel at 60 ºc are as follows: 64.1, 64.7, 64.5, 64.6, 64.5, 64.3, 64.6, 64.8, 64.2, and 64.3 j. a. use the student’s t distribution to find a 95% confidence interval for the impact energy of a238 steel at 60 ºc. b. use the student’s t distribution to find a 98% confidence interval for the impact energy of a238 steel at 60 ºc.

At 95% confidence interval, the lower end is 64.306 and the upper end is 64.614

At 98% confidence interval, the lower end is 64.268 and the upper end is 64.652

Step-by-step explanation:

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
