Answer:
The noise was reduced by 5.7884 decibels
Explanation:
Using the percentage-decibel table, the 95% decibel level y obtained by interpolation
Percentage Decibel
75 4.86
95 y
100 6.0205
95-75/100-75 = y-4.86/6.0205-4.86
0.8 = y-4.86/1.1605
y-4.86 = 0.8×1.1605
y - 4.86 = 0.9284
y = 4.86+0.9284 = 5.7884 decibels
All of the above
Useless information from last year now actually being useful:)

Answer:
More student may have taken the test in the afternoon than in the morning.
Explanation:
Mrs. Orlof teaches two history classes, one in the morning and one in the afternoon. Yesterday she gave the same test to both classes. Anyone who failed the test must take a retest. Since a greater percentage of students who took the morning test failed the test than students who took the afternoon test, more of Orloff’s morning history students than afternoon history students will have to take the retest. The conclusion above is not necessarily valid because more student may have taken the test in the afternoon than in the morning.
Answer:
The process that would allow skeptics to assess the reliability of these findings would be if a group of scientists carried out scientific research with the same variables and demonstrated the same result that proved that vaccines cause autism, based on scientific and testable facts.
Explanation:
In 1998 a British doctor named Dr. Andrew Wakefield stated in a scientific paper published in England that Autism could be caused by the triple viral vaccine, but this is not true because many other scientific researches were carried out to confirm this statement, and it was clear just the opposite, that vaccines cannot cause autism. In addition, it was also shown that the study author had serious problems in the methodology of how the study was carried out and had proven conflicts of interest in court. The doctor was guilty of ethical, medical and scientific misconduct for publishing a fraudulent study.
For this reason, for people who do not believe that vaccines cause autism to start believing, it would be necessary for a group of scientists to carry out scientific research with a correct methodology, with testable variables and all demonstrate the same result that could be proven by scientific facts.
