Reconsider the percentage of titanium in an alloy used in aerospace castings from exercise 8-52. recall that s = 0.37 and n = 51. (a) test the hypothesis h0 : σ = 0.25 versus h1 : σ ≠ 0.25 using α = 0.05.
(a) state any necessary assumptions about the underlying distribution of the data.
(b) find the p-value.
(c) explain how you could answer the question in part (a) by constructing a 95% two-sided confidence interval for σ.

step-by-step explanation:

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

answer
