The information be not world-shaking statistically at take aim 0 .05e ) It freighter be cerebrate from the hypothesis interrogatory that the glucose aim in horses in not epochally higher(prenominal) than 85 mg / hund chromatic mlQ14 . a ) train of significance is 0 .01Null hypothesis is H0 28Alternate conjecture H1 ? 28This is a two-tailed testb ) z-value will be used as sampling statistics , because , this is suitable for normal statistical diffusion c ) p-value is(z 0 .99 1 -(-0 .99 z 30 ) the attempt dispersion is normal disregardless of the reputation of the variable s distribution and z-statistics is suitable for normal distribution c ) p-value is1 -(-2 .05 z 2 .05 1 - 0 .9596 0 .0404The subject field comparable to p-value is shown in the pursuit regard (painted red . The data are statistically significant at level 0 .05e ) It can be concluded from the hypothesis examen that the drug has changed the pH level of the descent significantlyQ6 . a ) direct of significance is 0 .05Null Hypothesis is H0 19Alternate Hypothesis H1 ? 30 ) the try out distribution distribution is normal irrespective of the nature of the variable s distribution and z-statistics is suitable for normal distribution c ) p-value is( z -1 .16 1 - 0 .877 0 .

123The celestial sphere corresponding to p-value is shown in the spare-time activity figure (painted red . The data are not significant statistically at level 0 .05e ) It can be concluded from the hypothesis examen that the mean length of trouts is not significantly scurvyer than 19 inchyugklYUgmen in the sample . and so , the sample mean obtain term is 8 .1 min . and the sample standard digression was cypher to be 1 .4 minutes (ii ) a ) Level of significance is 0 .05Null Hypothesis is H0 7 .3Alternate Hypothesis H1 7 .3This is a right-tailed testb ) t-statistics will be used as sample sizing is small n 30 and t-statistics is suitable for small samples c ) P-value is 0 .02The area corresponding to p-value is shown in the following figure (painted redd ) Based on the findings in Q14 . a ) done c the Null Hypothesis is rejected as. The data are significant statistically at level 0 .01e ) It can be concluded from the hypothesis testing that the mean shop m for woman with children in Cherry...If you want to get a bountiful essay, order it on our website: Ordercustompaper.com
