A high school increased the length of the school day from 6.5 to 7.5 hours. Students who wished to attend this high school were

required to sign contracts pledging to put forth their best effort on their school work and to obey the school rules; if they did not wish to do so, they could attend another high school in the district. At the end of one year, student performance on statewide tests had increased by ten percentage points over the previous year. Does this improvement prove that a longer school day improves student achievement? No Yes

Answer:

Step-by-step explanation:

No

The time spent in school is only one factor. There are others.

1. They are required to sign contracts. These contracts state that

  • They must put forth their best effort.
  • They must obey school rules.
  • They had the option of going elsewhere. Their attendance at that school was a privilege not a right.
  • The students were subjected to an attitude that the school had within its walls.

2. Likely the students did so well was because, they had privileges not rights.

A survey of 70 students from a high school is conducted. From this sample, it is found that 58 students have sent a text message
Irina-Kira [14]
Number of students who have sent a text message only is given by the difference between those that have sent a text message and those that have done both.
i.e. Number of students who has sent a text message only = 58 - 12 = 46

Number of students who have uploaded a selfie only is given by the difference between those that have uploaded a selfie and those that have done both.
i.e. Number of students who have uploaded a selfie only = 21 - 12 = 9

The total number of students surveyed is 70.
Let the number of students who have neither sent a text message nor taken a selfie today  be x, then
46 + 9 + 12 + x = 70
67 + x = 70
x = 70 - 67 = 3

Therefore, 3 students neither sent a text message nor taken a selfie today.

The number of students that have sent a text message or have taken a selfie today is given by the sum of the number of students that have sent a text message and the number of students that have taken a selfie less the number of people that have done both.
i.e. number of students that have sent a text message or have taken a selfie today = 58 + 21 - 12 = 67.
