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

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
