The amount of lateral expansion (mils) was determined for a sample of n = 9 pulsed-power gas metal arc welds used in lng ship containment tanks. the resulting sample standard deviation was s = 2.84 mils. assuming normality, derive a 95% ci for ? 2 and for ? . (round your answers to two decimal places.)

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

the answer is 489
