Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis against using a random sample of specimens. calculate the p-value if the observed statistic

P-value= 0.028834

Step-by-step explanation:

The test statistic value is: 11.25 12 -3 0.5

Since this is a left tailed test, so the p-value is given by:

P(t-1 3 P(t3<-3)=P(t3 > 3) = 0.028834

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
