We record the amount of time (xin minutes) per day that a group of 12 high school students spend using their cell phone (texting, talking, and web use). We also record the overall GPA (y) of each student. Following is a regression summary for these data:

​

The regression equation is

GPA = 4.01 - 0.0153 CellTime

​

Predictor     Coef SE       Coef       T       P

Constant       4.0084     0.2486    6.12   0.000

CellTime    -0.015334   0.003226   -4.75   0.001

​

S = 0.472864 R-Sq = 69.3% R-Sq(adj) = 66.3%

Source           DF       SS      MS        F       P

Regression        1   5.0519   5.0519   22.59   0.001

Residual Error   10   2.2360   0.2236

Total            11   7.2879

​

What is a 90% confidence interval forβ0, the mean GPA of high school students who spent no time using their cell phone?

Alzheimer's disease affects only about 10% of people older than 65 years of age. Most forms of decreased mental function and dementia are caused by disuse (letting the mind get lazy).

The most destructive flu epidemic of all times in recorded history occurred in 1918, with approximately 20 million deaths worldwide.

Many medications that are used to treat infertility are injected subcutaneously. This is easy to do using the anterior abdomen as the site of injection but avoiding the area directly around the belly button.

Did you know?

Intradermal injections are somewhat difficult to correctly administer because the skin layers are so thin that it is easy to accidentally punch through to the deeper subcutaneous layer.

Did you know?

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
