Arivet is to be inserted into a hole. a random sample of n 15 parts is selected and the hole diameter is measured. the sample standard deviation is strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeters? use α-0.01. (a) calculate the test statistic xo round your answer to two decimal places (e. g. 98.76) 0.008 millimeters. is there (b) is there strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeters yes. statistical tables and charts the tolerance is +/-296

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
