Answer:
A- Using real world problems to help students learn to solve them on their own
Explanation:
"Problem-based learning" is a teaching approach that centers on students. It allows the student to learn on their own or to solve problems on their own. This is also based on their own <em>"reasoning"</em> and <em>"reflection." </em> So, the role of the teacher here is to facilitate or guide the students. He doesn't need to provide direct instruction to the student. The goal here is "self-identified," so this means that the <u>students identity their own goals.</u> Real word problems are used in order for the students to learn how to solve them on their own.
So, this explains the answer.
Answer:
A) 20%.
B) 26.66%.
C) 40%.
Step-by-step explanation:
Since at the Virgin Music store in Times Square, 60 people entering the store were selected at random and were asked to choose their favorite type of music, and of the 60, 12 chose rock, 16 chose country, 8 chose classical, and 24 chose something other then rock, country, or classical, to determine the empirical probability that the next person entering the store favors (a) rock music, (b) country music, and (c) something other then rock, country, or classical music, the following calculation must be performed:
A)
60 = 100
12 = X
12 x 100/60 = X
1200/60 = X
20 = X
Therefore, the probability that the next person favors rock music is 20%.
B)
60 = 100
16 = X
16 x 100/60 = X
1600/60 = X
26.66 = X
Therefore, the probability that the next person favors country music is 26.66%.
C)
60 = 100
24 = X
24 x 100 / 60 = X
2400 / 60 = X
40 = X
Therefore, the probability that the next person favors another type of music is 40%.
Answer:
1.070,0.1003
Step-by-step explanation:
Given that a random sample of n=1400 registered voters and found that 720 would vote for the Republican candidate in a state senate race.
p = the proportion of registered voters who would vote for the Republican candidate.
Sample proportion =
Hypotheses are:
(Right tailed test )
p difference =
Assuming null hypothesis to be true,
Std error =
a) Test statistic Z = p difference/std error = 1.070
b) When z =1.28, p value = 0.100273
