Answer: The value of test statistic = -10.67

Step-by-step explanation:

Test statistic for proportion:

z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}

, where p= population proportion

n= sample size

\hat{p} = sample proportion

AS per given,

p=0.94, n= 1004, \hat{p}=0.86

z=\dfrac{0.86-0.94}{\sqrt{\dfrac{0.94(1-0.94)}{1004}}}\\\\=\dfrac{-0.08}{\sqrt{\dfrac{0.0564}{1004}}}\\\\=\dfrac{-0.08}{\sqrt{0.0000561752988048}}\\\\=\dfrac{-0.08}{0.00749501826581}\\\\=-10.673756509\approx-10.67

i.e. the value of test statistic = -10.67

The dot plots below show the scores for a group of students for two rounds of a quiz:
Anarel [89]

Answer:

first of all the answer should be A. the range of round 2 is greater than the round 1 range because first of all range is the subtraction of the maximinium and the lower number so 1 is for the round 1 range score and for the round 2 scores the range is 4.

5-4= 1 for round 1 range score

5-1=4 for round 2 range score.

B and c cannot be because the score for round 2 is lower and for round 1 the scores are more higher and option d also cannot be because there is overlap so option a is the correct answer and have a great day.

Step-by-step explanation: Hopefully that is the correct answer and please give me brainliest if you want.
