Answer:

The confidence interval for a population mean proportion mean should be constructed because the variable of interest is time to complete the round, which is a quantitative variable.

Step-by-step explanation:

A researcher with a golf association obtained a random sample of 25 rounds of golf on a Saturday morning and recorded the time it took to complete the round.

Time is the number of hours, so it is mean, and not proportion.

Variable of interest is time to complete the round, and since it is measured in hours it is a quantitative variable.

The answer is:

The confidence interval for a population mean proportion mean should be constructed because the variable of interest is time to complete the round, which is a quantitative variable.

Solve <br><br> 2k(-3k + 4) + 6(k2 + 10) =k(4k + 8) - 2k(2k + 5). <br><br> Check your solution.
Artist 52 [7]

Answer:

k=\frac{-52}{18} \approx -2.89 (2dp)

Step-by-step explanation:

2k(-3k + 4) + 6(k^2 + 10) =k(4k + 8) - 2k(2k + 5)

Expand brackets:

-6k^2+8k+6k^2+60=4k^2+8-4k^2-10k

simplify:

8k+60=8-10k

Collect terms:

18k=-52\\

Rearrange for k:

k=\frac{-52}{18}

Which Quaker belief do you think influenced William Penn’s attitude toward Native Americans? Explain your answer.
Lapatulllka [165]

Answer:

Penn and other Quakers believed that everyone had to seek God in his or her own way.  Penn also thought that religious tolerance – or “liberty of conscience” – would create stronger governments and wealthier societies.  Other English thinkers in the 1600s shared these ideas.  But Penn had the opportunity to act on his beliefs. In Pennsylvania, religious tolerance was the law.

Penn welcomed settlers from all faiths to Pennsylvania.  Each of the other American colonies had established an official church, but Penn did not.  He sought out religious groups suffering in Europe, and invited them to his colony.  He even gave some groups land.  Yet religious tolerance did not mean that colonists of all faiths had equal rights.  Only Christians could vote or hold political office.  But all settlers could take part in the social and economic life of Pennsylvania.

Penn’s belief that “Religion and Policy…are two distinct things, have two different ends, and may be fully prosecuted without respect on to the other” took hold and became one of America’s most important ideals.
