A survey of an urban university (population of 25,450) showed that 870 of 1,100 students sampled supported a fee increase to fun
Katen [24]

Answer:

95% confidence interval for the proportion of students supporting the fee increase is [0.767, 0.815]. Option C

Step-by-step explanation:

The confidence interval for a proportion is given as [p +/- margin of error (E)]

p is sample proportion = 870/1,100 = 0.791

n is sample size = 1,100

confidence level (C) = 95% = 0.95

significance level = 1 - C = 1 - 0.95 = 0.05 = 5%

critical value (z) at 5% significance level is 1.96.

E = z × sqrt[p(1-p) ÷ n] = 1.96 × sqrt[0.791(1-0.791) ÷ 1,100] = 1.96 × 0.0123 = 0.024

Lower limit of proportion = p - E = 0.791 - 0.024 = 0.767

Upper limit of proportion = p + E = 0.791 + 0.024 = 0.815

95% confidence interval for the proportion of students supporting the fee increase is between a lower limit of 0.767 and an upper limit of 0.815.

Can someone please help me with this? I’ve been struggling with this question for a while and is due soon! I’ll give brainliest
Fofino [41]

Answer: See below

Step-by-step explanation:

The transformation from triangle LMN to triangle L'M'N' is the reflection about the line y =x.

The line segment from L to y=x and the line segment from L' to line y=x are congruent.

Yes, we will get the same characteristic if we draw a line from point M to y=x and the line  from M' to y=x.

It is because points P', M' and N' are reflections of points P, M, and N respectively about the line y=x.

Graph 1 (attached as first picture)

Graphing a triangle LMN and reflecting it over the line y = x to create triangle L'M'N, we have:

The transformation from triangle LMN to triangle L'M'N' is the reflection about the line y =x.

Drawing a line from point L to the line y=x and from line L' to line y=x we have:

Graph 2 (attached as second picture)

The line segment from L to y=x and the line segment from L' to line y=x are congruent.

Yes, we will get the same characteristic if we draw a line from point M to y=x and the line  from M' to y=x.

It is because points P', M' and N' are reflections of points P, M, and N respectively about the line y=x.
