Use the information below to answer Questions 1 through 3.

Given a sample size of 34, with sample mean 660.3 and sample standard deviation 104.9, we

perform the following hypothesis test. Since n>30, this is a Z test.

Null Hypothesis

0

: 700H

Alternative Hypothesis

: 700

µ

What is the test statistic? What is the p-value?

The test statistic is,

Test statistic =

660.3−700

104.9

√

34

=−2.2068

The p-value is,

P-value = P (|Z|>2.2068) = 0.0273

At a 5% significance level (95% confidence level), what is the critical value(s)in this

test? Do we reject the null hypothesis?

At 5% significance level the critical value is ±Z (0.025) = ±1.96.

What are the border values of

x

between acceptance and rejection of this hypothesis?

As the critical values are ±1.96 so the border values of

́x

are

±

1.96∗104.9

√

=±35.2608

Questions 4 through7involve rolling of dice.

Given a fair, six-sided die, what is the probability of rolling the die twice and getting a

“1” each time?

As both dice throws are independent so the required probability would be the

multiplication of probabilities of getting 1 in the 1

st

and 1 in the 2

nd

throw.

So the required probability = 1/6*1/6 = 1/36.

What is the probability of getting a “1” on the second roll when you get a “1” on the first

roll?

As throws are independent so getting 1 in the 2

nd

does not depend on getting 1 on the 1

st

thus the required probability is getting 1 on the 2

nd

which is 1/6.

The House managed to load the die in such a way that the faces “2” and “4” show up

twice as frequently as all other faces. Meanwhile, all the other faces still show up with

equal frequency. What is the probability of getting a “5” when rolling this loaded die?

There are 6 faces in a dice. 2 and 4 has double probability so the probability of getting a 5

is 1/(6+2) = 1/8.

Write the probability distribution for this loaded die, showing each outcome and its

probability.

The probability distribution is given below,

Trees occur in various venues in computer science: decision trees in algorithms, search trees, and so on. In linguistics, one encounters trees as well, typically as parse trees, which are essentially sentence diagrams, such as those you might have had to do in primary school, breaking a natural-language sentence into its components—clauses, subclauses, nouns, verbs, adverbs, adjectives, prepositions, and so on. What might be the significance of the depth and breadth of a parse tree relative to the sentence it represents? If you need to, look up parse tree and natural language processing on the Internet to see some examples.
