Have not been prescribed atenolol the population

This preview shows page 11 - 14 out of 14 pages.

have not been prescribed Atenolol, the population systolic blood pressure meanis 165 (µ= 165) with a standard deviation of 6.The sample of30 individualswho take Atenololhave an average (mean) systolic blood pressure of 147.Onthe basis of these data, can the researcher conclude that theAtenololsignificantly lowers systolic blood pressure?Calculate the 95% confidence interval
What is the new critical value you will use for this calculation?
Question 311 out of 1 pointsA health care professional wants to determine whether individuals withhypertension who take Atenololhave significantly lower systolic blood pressurethan individuals with hypertension who do not take Atenolol. For individuals whohave not been prescribed Atenolol, the population systolic blood pressure meanis 169 (µ= 169) with a standard deviation of 7.The 30 individuals who takeAtenololhave an average (mean) systolic blood pressure of 163.On the basis ofthese data, can the researcher conclude that the Atenololsignificantly lowerssystolic blood pressure?(Use these numbers only for thisquestion!)Calculate the 95% confidence intervalAs you know, two values will be required to complete the following equation:_________ ≤ µ ≤ __________For this question, what is the value that is below or less than µ?
Question 320 out of 1 pointsA health care professional wants to determine whether individuals withhypertension who take Atenololhave significantly lower systolic blood pressurethan individuals with hypertension who do not take Atenolol. For individuals whohave not been prescribed Atenolol, the population systolic blood pressure meanis 172 (µ= 172) with a standard deviation of 22.The 30 individuals who takeAtenololhave an average (mean) systolic blood pressure of 157.On the basis ofthese data, can the researcher conclude that the Atenololsignificantly lowerssystolic blood pressure?(Use these numbers only for thisquestion!)Calculate the 95% confidence intervalAs you know, two values will be required to complete the following equation:_________ ≤ µ ≤ __________For this question, what is the value that is above or greater than µ?
Question 331 out of 1 pointsThe average time scheduled for a doctor’s visit is 21 minutes with a standarddeviation of 11 minutes. A researcher uses a sampling distribution made up ofsamples of size 352.(Use these numbers for this question only!)According to the Central Limit Theorem, what is the standard error of the mean?
Question 341 out of 1 pointsThe average time scheduled for a doctor’s visit is 41 minutes with a standarddeviation of 21 minutes. A researcher uses a sampling distribution made up ofsamples of size 275.(Use these numbers for this question only!)According to the Central Limit Theorem, what is the mean of the samplingdistribution of means?
