You work for a biomedical engineering start-up that uses a titanium alloy to manufacture hip joints. The femoral head for the joint needs to be precision machined to fit the corresponding socket in the pelvis with an intended diameter of 45 mm and a standard deviation no greater than 0.5 mm. To test the manufacturing process, the following data have been collected. x1 x2 x3 x4 x5 x6 x7
44.7753 44.35068 45.21798 45.01032 45.63969 45.13967 44.79558

Required:
a. Perform a Hypothesis Test to determine if there is sufficient evidence to reject the claim that the mean of the manufacturing process is sufficient to a significance level of α = 0.05.
b. Perform a Hypothesis Test to determine if there is sufficient evidence to reject the claim that the standard deviation of the manufacturing process is sufficient to a significance level of α = 0.05.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.

factor trees are nice.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
