Answer:

The most appropriate inferential statistic test in the present situation is the;

b. Two-sample t-test

Step-by-step explanation:

From the question, we have;

The number of subjects in each sample, n₁ = 100

The number of samples = 2

The nature of the test = To compare the two means

The value of the population standard deviation, σ = Unknown

From the given parameters, we have;

The t-test is a method of inferential statistics for determining whether the difference between the mean of two groups is significant, that is if the observed difference are due to chance, where the groups are likely to have some characteristics that are related

The t-test is utilized when testing an hypothesis, and it is used for small samples, where the population standard deviation is unknown

The types of t-test used are;

a) One-sample t-test

b) Two-sample t-test

c) Paired Sample t-test

Therefore, a two-sample t-test is most appropriate.

Answer:

d

Step-by-step explanation:

in order for it to be a triangle the angles have to add up to equal 180

5+75+100=180 so its not a

10+80+90=180 so its not b

20+60+100=180 so its not c

45+45+45=135 so its d because the angles dont add up to 180

50+50+80=180 so its not e

John makes 35% of his free throw shots.
Minchanka [31]

Answer:

(1)0.39

(2)0.14

(3)0.21

(4)0.26

Step-by-step explanation:

John makes 35% of his free throw shots.

  • The probability that John makes his shot =0.35
  • The probability that John misses his shot =1-0.35=0.65

Sue makes 40% of her free throw shots.

  • The probability that Sue makes her shot =0.4
  • The probability that Sue misses her shot =1-0.4=0.6

(1)John and sue both miss their shots

P(John and sue both miss their shots)

=P(John miss his shot) X P(Sue misses her shot)

=0.65 X 0.6 =0.39

(2)John and Sue both make their shots

P(John and Sue both make their shots)

=P(John makes his shot) X P(Sue makes her shot)

=0.35 X 0.4=0.14

(3)John makes his shot and Sue misses  hers

P(John makes his shot and Sue misses  hers)

=P(John makes his shot) X P(Sue misses her shot)

=0.35 X 0.6=0.21

(4)John misses his shot and Sue makes  hers

P(John misses his shot and Sue makes  hers)

=P(John miss his shot) X P(Sue makes her shot)

=0.65 X 0.4 =0.26
