<span>The right answer is a. greater; slower. According to various investigations on operant conditioning, this is because learning occurs immediately after observation and imitation of a behavior. <span>If reinforcement is delayed, the learning time will have passed and a learning situation is less likely to occur.

I hope my answer can help you.

A survey asked 26 adults how many years of education they had. The sample mean was 13.03 with a standard deviation of 3.22. It i

Answer: (11.95, 14.11)

Explanation:

Let x be a random variable that represent the number of years of education.

Given: Sample size : n= 26

Sample mean : $\overline{x}=13.03$

Sample standard deviation : s = 3.22

Significance level : $\alpha=100\%-90\%=10\%=0.1$

Degree of freedom: df = n-1 = 25

Critical t-value for $\alpha=0.1$ and df = 25 will be

$t_{\alpha/2, df}=t_{0.05,25}=1.7081$

90% confidence interval for mean:

$\overline{x}\pm t_{\alpha/2,df}\dfrac{s}{\sqrt{n}}\\\\=13.03\pm (1.7081)\dfrac{3.22}{\sqrt{26}}\\\\=13.03\pm (1.7081)\dfrac{3.22}{5.09902}\\\\=13.03\pm 1.08\\\\=(13.03-1.08,\ 13.03+1.08)\\\\ =(11.95,\ 14.11)$

A 90% confidence interval for the mean number of years of education = (11.95, 14.11)

Debates are an important part of the election process. True or False

marissa [1.9K]

True

Explanation:

Political communication allows one country's political processes to be considered and debated.
Through political communication, citizens who are not directly involved in the political process gain new insights and information on the functioning of political processes in the country and their elected representatives.
There are always three parties involved in the political communication process: government actors, the media and citizens, or the political public.
The degree to which they are involved in political communication also determines the way in which a country's overall policy works.
