The National Electronic Injury Surveillance System tracks injuries reported from
hospital admissions across the United States (Consumer Product Safety Commission
2018). For the data in 2017, we extracted all incidences of hand injuries that
referenced punching a wall. There were 1843 such cases. The surveillance system also
records some of the properties of the patients, including gender. Of all cases where a
person was admitted to a hospital for injuries from punching a wall, 1352 were
recorded as male and 491 were recorded as female.
a. Do an appropriate hypothesis test to ask whether the proportion of males among
wall-punchers is 50%.
AJ’s sleep pattern had been fluctuating due to stress and diet, so he started to keep a diary of how many hours he slept each night. On the 4th night after he started the diary, AJ slept 9.4 hours, which was the most sleep he got any night. Gradually, he got less sleep each successive night until, on the 18th night after he started the diary, AJ slept 6.2 hours, which was the least sleep he got any night. After keeping his diary for 6 months, he realized that the number of hours he got each night followed a sinusoidal curve. Let t be the number of nights since he started his diary, and s be how many hours he slept that night. It may be helpful to draw a crude sketch of the sleep time function and label the known t − and s − values on it. POSITIVE or NEGATIVE SIN or COS Maximum s − value = Minimum s − value = ______________ ______________ Middle s − value = ______________ = D Amplitude = ______________ = A ⇒ B = ______________ Given the crude sketch of the height function, the…
An Internet advertising agency is studying the number of "hits" on a certain web site during an advertising campaign. It is hoped that as the campaign progresses, the number of hits on the web site will also increase in a predictable way from one day to the next. For 10 days of the campaign, the number of
hits × 105
is shown.

(a) To construct a serial correlation, we use data pairs
(x, y)
where x = original data and y = original data shifted ahead by one time period. Construct the data set
(x, y)

The teacher decided that she wanted to conduct a study to see if the number of SnapChats a student sends per day affects how much time students talk to their friends face-to-face. So, the teacher let her 2nd period class continue sending Snaps as they always have. Then, the teacher told her 5th period that they were to not watch use SnapChat for a whole day. Then, the teacher had students record how many conversations they had with their friends during the week, gathered the data, and analyzed the results. f.

She randomly divides twenty-four students into three groups of eight. All students study a passage of text for 30 minutes. Those in group 1 study with background sound at a constant volume in the background. Those in group 2 study with noise that changes volume periodically. Those in group 3 study with no sound at all. After studying, all students take a 10 point multiple choice test over the material. Their scores follow: Group test scores 1) constant sound 7 4 6 8 6 6 2 9 2) random sound 5 5 3 4 4 7 2 2 3) no sound 2 4 7 1 2 1 5 5 Calculate the Between-Subject One-Way ANOVA, make sure you include all the steps and show your calculations.
