Assume that a simple random sample has been selected and test the given claim. Use the diastolic blood pressure measurements​ (in mm​ Hg) for adult females listed in the accompanying data table and test the claim that the adult female population has a mean diastolic blood pressure level less than 90mm Hg. Suppose a diastolic blood pressure above 90 is considered to be hypertension. Use a 0.10 significance level. Based on the​ result, can we conclude that none of the adult females in the sample have​ hypertension? 699679657181595074886958716464885583726370728972666772837489617175928662798177847559657660666452677262717865866095577575587964914646677157726873706673647157578271726565835476745291568383786871618957777689637181437274447187806867717965976770636768756169525568677475407354697865736368549470658553   Identify the value of the test statistic.   Identify the​ P-value.
