1) A group of 41 college students from a certain liberal arts college were randomly sampled and asked about the number of alcoholic drinks they have in a typical week. The purpose of this study was to compare the drinking habits of the students at the college to the drinking habits of college students in general. In particular, the dean of students, who initiated this study, would like to check whether the mean number of alcoholic drinks that students at his college in a typical week differs from the mean of U.S. college students in general, which is estimated to be 4.73.
The group of 41 students in the study reported an average of 4.44 drinks per with a standard deviation of 3.55 drinks.
Find the p-value for the hypothesis test.
The p-value should be rounded to 4-decimal places.
2) Commute times in the U.S. are heavily skewed to the right. We select a random sample of 520 people from the 2000 U.S. Census who reported a non-zero commute time.
In this sample, the mean commute time is 28.1 minutes with a standard deviation of 19.2 minutes. Can we conclude from this data that the mean commute time in the U.S. is less than half an hour? Conduct a hypothesis test at the 5% level of significance.
What is the p-value for this hypothesis test?
(Your answer should be rounded to 4 decimal places.)
3) Dean Halverson recently read that full-time college students study 20 hours each week. She decides to do a study at her university to see if there is evidence to show that this is not true at her university. A random sample of 34 students were asked to keep a diary of their activities over a period of several weeks. It was found that the average number of hours that the 34 students studied each week was 17.9 hours. The sample standard deviation of 4.6 hours.
Find the p-value.
The p-value should be rounded to 4-decimal places.

The acceleration at which the block falls is uniform .
That allows us to use kinematic equations along the
y-direction to determine an equation for time.
Then, solving for time in terms of h and v f,
we get that
also .This problem also allows us to investigate the
angular portion of the spool, which is spinning without slipping as
the block is accelerating downwards.
What is an expression for the angular displacement the
spool goes through while the block is in motion?
(F1) θ = 2 g h 2 R v f 2
(F2) θ = h R
(F3) θ = 1 4

INSTRUCTIONS: Answer the subsequent set of questions to
solve the "Goal" of this problem. We recommend you write out your
answer to compare to the particular questions as you go along.
SETUP: As shown in the figure, a box of mass m is attached to a light string that is wrapped around a cylindrical spool of radius R and mass M. The spool is suspended from the ceiling. Then, the box is released from rest a distance h above the floor.
FIGURE:
GOAL: Determine an expression for the amount of
time it takes for the box to reach the floor
PART A - Totalinitial energy
We will start with energy conservation to solve this problem. Take the floor as our vertical "zero".
After removing all components that either cancel or equal "0", what does the total INITIAL energy look like?
(A1) K i only
(A2) K r o t i only
(A3) U g r a v i only
(A4) W o t h e ronly
(A5) K i + K r o t i
(A6) K i + K r o t i + U g r a v i
(A7) K i + K r o t i + U g r a v i + W o t h e r
(A8) K i + U g r a v i

PART B - Total final energy
Following the same outline as previous, after removing all components that do not change or that equal "0", what does the total FINAL energy look like?
(B1) K f only
(B2) K r o t f only
(B3) U g r a v f only
(B4) W o t h e r only
(B5) K f + K r o t f
(B6) K f + K r o t f + U g r a v f
(B7) K f + K r o t f + U g r a v f + W o t h e r
The acceleration at which the block falls is uniform
(can you think of why?). That allows us to use kinematic
equations along the y-direction to determine an equation for
time.
Then, solving for time in terms of h and v f,
we get that

The urgent care manager must resubmit her budget based on 2018 projected visits. The 2018 budget should be based on actual expenses and visits incurred during the first seven months of 2017. Cost standards (2017) and budget standards (2018) must be prepared for all variable costs (indicated by a V behind the object code description). All fixed costs (F) should be projected using the incremental budgeting methodology. Projected visits is 2018 is 52,560. Salary and fringe benefit (object codes 4000-4199) increases for all personnel should be estimated at 4.0% except for health insurance (4120) which is expected to increase by 8%. Input price increases for supplies and other costs (4200-4960) should be increased by 3% except for medications, 5% increase and profession insurance, 10%. All increases are effective January 1, 2015. The budget report, BudgetCh06, Problem 6.1 tab, shows the urgent care centers expenses for 2016 and the actual and budgeted expenses for the first seven months of 2017. The CEO has requested all department heads submit their 2015 operating budget by Wednesday, March 21, 2014. The 2018 fiscal year begins January 1, 2018.
