A random sample of size nequals500 yielded ModifyingAbove p with caretequals0.30. a. Is the sample size large enough to use the large sample approximation to construct a confidence interval for p? Explain. b. Construct a 95% confidence interval for p. c. Interpret the 95% confidence interval. d. Explain what is meant by the phrase "95% confidence interval."

15 points! write the slope-intercept form of the equation of the line through the given point with the given slope. use y-y = m(x-x) to solve. through (2,5) slope= undefined

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 upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).

Can you me find the missing length. i attached an image.
