1. Coffee. A student wanted to determine if there is a difference in the number of calories between comparable coffee drinks at Starbucks and Seattle's Best Coffee (SBC), two major coffee retailers. She found caloric information about 10 different drinks and created the table shown below:
| Drink | Starkbucks | SBC |
| Cappucino | 120 | 130 |
| Latte | 190 | 160 |
| Vanilla Latte | 250 | 240 |
| Iced Latte | 130 | 140 |
| Mocha | 260 | 390 |
| White Chocolate Mocha | 400 | 310 |
| Peppermint Mocha | 330 | 410 |
| Iced Mocha | 200 | 240 |
| Hot Chocolate | 300 | 320 |
| Chai Tea Latte | 240 |
230 |
Conduct an appropriate hypothesis test to investigate whether, on average, there is a difference in calories between comparable drinks at Starbucks and SBC. Be sure to state hypothesis using proper notation, check conditions, compute a P-value, and state a conclusion.
2. Another Cup. Construct a 90% confidence interval for the mean difference in number of calories between comparable beverages at Starbucks and SBC. Be sure to check conditions, express the interval using proper notation, and include a sentence explaining the meaning of the interval.

A clinical psychology student wanted to determine if there is a
significant difference in the Picture Arrangement scores (a subtest
of the WAIS-IV that some feel might tap right-brain processing
powers) between groups of right- and left-handed college students.
The scores were as follows:

A baseball fan wanted to know if there is a difference between
the number of games played in a World Series when the American
League won the series versus when the National League won the
series. From 1922 to 2012, the population standard deviation of
games played in World Series ultimately won by the American League
was 1.14, and the population standard deviation of games played in
World Series ultimately won by the National League was 1.11. In 19
randomly...

In the laboratory a student uses a "coffee cup" calorimeter to
determine the specific heat of a metal. She heats 18.3 grams of
gold to 99.38°C and then drops it into a cup containing 80.2 grams
of water at 20.87°C. She measures the final temperature to be
21.40°C. Assuming that all of the heat is transferred to the water,
she calculates the specific heat of gold to be J/g°C.

The management of a soda company wanted to determine the average
number of ounces of soda consumed per resident in the state of
Pennsylvania. Past trends indicate that the variation in soda
consumption (σ) was 4 ounces. A 95% confidence level is required,
and the error is not to exceed +/- 1/2 ounce. (a) What sample size
would you recommend? Show your calculations. (b) The management
wanted an estimate twice as precise as the initial precision level
and an increase...

3) If you wanted to determine whether there is a relationship
between “the number of steps one walks during a given week” and
“score on a neuroticism test” using the correlation method of
research,
3a) Give one variable that would likely be positively correlated
with “number of steps walked”.
3b) Give one variable that would likely be negatively correlated
with “number of steps walked”. (Don’t use the same variables as in
3C)
3c) If the correlation coefficient between “number of...
