When conducting an ANOVA on sbp and genhelth, the p-value is 0.02. Therefore we conclude reject the null hypothesis at 1% level, mean sbp different for all categories of genhelth no evidence to reject the null hypothesis of equal means reject the null hypothesis at 5% level, mean sbp different for all categories of genhelth reject the null hypothesis at 5% level, mean sbp different for at least one category of genhelth

A test of hypothesis will be conducted to determine if there is enough evidence to conclude that the average time required to type a certain memorandum is faster if female secretaries are using computers rather than typewriters using a 5% level of significance. What is the appropriate null hypothesis? a)The average time required to type a certain memorandum is less than or equal to if female secretaries are using computers rather than typewriters. b)The average time required to type a certain memorandum is lesser if female secretaries are using computers rather than typewriters. c)The average time required to type a certain memorandum is greater if female secretaries are using computers rather than typewriters. d)The average time required to type a certain memorandum is different if…In a random sample of males, it was found that 18 write with their left hands and 209 do not.

She collected data from a randomsample of 150 adults and found 14 of the adults in the sample wereobese. It is claimed that 13% of adults globally are obese.(a) State an appropriate null and alternative hypotheses for the study.(b) Using a 5% significance level, obtain the test statistic for thehypothesis you proposed for part (a), clearly stating anyassumptions you have made. (c) The exact p-value associated with the hypothesis for the study is0.186. What should the researcher’s conclusion be based on thisvalue?A researcher claims that the difference between the proportion of male athletes and that of female athletes in a certain university who live in osaka is far from 7.25%. 285 male athletes have been selected at random, and 113 of them reside in osaka.

After the inspection, he found that 15 calculators were defective. Find the UCL and the LCL, by using 2-sigma (z=2). Hint: Sample size is known (n=100)and , the inspection has two possible outcomes (i.e., undefective and defective). In other words, average percentage error can be calculated.
