Questions

(5pts) Discuss if you saw a buffer. Define buffer and explain, with complete sentences, what you did to shift that buffer.

(10pts) A buffer was established with 2.0mL of 0.833M acetic acid. 0.5mL of 0.1M HCl is added. What is the new pH of the buffer? Ka of acetic acid = 1.8 x 10-5 Show your work.

Discuss in a complete sentence how your theoretical calculation here is the same or different than what was obtained in Data Table 5.

A behavior analyst would like to evaluate the effectiveness of a new technique for controlling classroom outbursts of unruly children.

Can someone please USE SPSS and show me their analysis?

A behavior analyst would like to evaluate the effectiveness of a new technique for controlling classroom outbursts of unruly children. For a sample of n=4 children the number of outbursts is recorded 1 day before treatment and again 1 week, 1 month and 6 months after treatment. The data are as follows:

Child --Before-- 1 week --1 month-- 6 months

A --8 --2-- 1-- 1

B-- 4 --1 --1 --0

C--6-- 2-- 0-- 2

D-- 8-- 3 --4 --1

Use a repeated measures ANOVA with alpha = .05 to determine whether there are significant changes in behavior over time (write all the steps involved in testing the hypothesis). Use SPSS to solve this problem. Please make sure to show all the steps of hypothesis testing.

Pascal’s triangle looks as follows:

1

1 1

1 2 1

1 3 3 1

1 4 6 4 1

...

The first entry in a row is 1 and the last entry is 1 (except for the first row which contains only 1), and every other entry in Pascal’s triangle is equal to the sum of the following two entries: the entry that is in the previous row and the same column, and the entry that is in the previous row and previous column.

Use dynamic programming to design an O(n2) time algorithm that computes the first n rows in Pascal’s triangle.
