An investigator theorizes that people who participate in a regular program of exercise will have levels of systolic blood pressu

Nata [24]

Answer:

a) H0: mean of exercise group = mean of non exercise group

Ha: mean of exercise group ≠ mean of non exercise group

b) p value is 0.002

c) see the explanation

d) Null hypothesis is rejected. Ha is true

Explanation:

The complete question is:

An investigator theorizes that people who participate in a regular program of exercise will have levels of systolic blood pressure that are significantly different from that of people who do not participate in a regular program of exercise. To test this idea the investigator randomly assigns 21 subjects to an exercise program for 10 weeks. After ten weeks the mean systolic blood pressure of subjects in the exercise group is 137 and the standard deviation of blood pressure values in exercise group is 10. After ten weeks the mean systolic blood pressure of subjects in the non-exercise group is 127 and the standard deviation of blood pressure values in exercise group is 9.

a) State null and alternate hypothesis

b) Include the critical value of appropriate as part of decision rule to for rejecting the null hypothesis

c) show all of your work in reaching a decision as to whether the investgator should reject the null hypothesis or not.

d) State the conclusion te investigator is entitled ot draw on the basis of results

a) H0: mean of exercise group = mean of non exercise group

Ha: mean of exercise group ≠ mean of non exercise group

b) at 5% significance value, the p vaue is 0.002

t= (x1 — x2) /√ (σ1² / √n1 + σ2² / n2),

x1: mean of exercise group

x2: mean of non exercise group

σ1: standard deviation of exercise group

σ2: standard deviation of non exercise group

N1: sample size of exercise group

N2: sample size of non exercise group

t= 4.948

p value is 0.002

Since p value is less t statistic, null hypothesis is rejected.

Ha is true

Was president Andrew Jackson Democratic or undemocratic and list at least 10 facts on both sides

nikdorinn [45]

Such tendentious revisionism may provide a useful corrective to older enthusiastic assessments, but it fails to capture a larger historical tragedy: Jacksonian Democracy was an authentic democratic movement, dedicated to powerful, at times radical, egalitarian ideals—but mainly for white men.

Socially and intellectually, the Jacksonian movement represented not the insurgency of a specific class or region but a diverse, sometimes testy national coalition. Its origins stretch back to the democratic stirrings of the American Revolution, the Antifederalists of the 1780s and 1790s, and the Jeffersonian Democratic Republicans. More directly, it arose out of the profound social and economic changes of the early nineteenth century.

Recent historians have analyzed these changes in terms of a market revolution. In the Northeast and Old Northwest, rapid transportation improvements and immigration hastened the collapse of an older yeoman and artisan economy and its replacement by cash-crop agriculture and capitalist manufacturing. In the South, the cotton boom revived a flagging plantation slave economy, which spread to occupy the best lands of the region. In the West, the seizure of lands from Native Americans and mixed-blood Hispanics opened up fresh areas for white settlement and cultivation—and for speculation.

Not everyone benefited equally from the market revolution, least of all those nonwhites for whom it was an unmitigated disaster. Jacksonianism, however, would grow directly from the tensions it generated within white society. Mortgaged farmers and an emerging proletariat in the Northeast, nonslaveholders in the South, tenants and would-be yeomen in the West—all had reasons to think that the spread of commerce and capitalism would bring not boundless opportunities but new forms of dependence. And in all sections of the country, some of the rising entrepreneurs of the market revolution suspected that older elites would block their way and shape economic development to suit themselves.
