Answer #1

5) When considering our alternative hypothesis, words synonymous with "larger, more, higher, further, bigger" would be suggest Right tail test

option D

6. When considering our alternative hypothesis, words synonymous with "smaller, fewer, lower, decrease" wpould suggest Left tail test

option A

7. Which is not a step in the hypothesis test process:Calculate Range

In Hypythesis we do all steps expect Range

Option E

8)The critical value separates the Non Critical Region from the Critical Region

option D

A hypothesis test is conducted. In this hypothesis test, the
alternative hypothesis is that more than 40% of the population
wears a helmet while riding a bicycle. When the p-value
for the hypothesis test is calculated, it is reported to be 0.24.
Which statement below is a correct conclusion to be drawn from this
information?
A. We can conclude that more than 40% of the population wears a
helmet while riding a bicycle.
B. We cannot conclude that more than...

A 0.01 significance level is used for a hypothesis test of the
claim that when parents use a particular method of gender
selection, the proportion of baby girls is different from 0.5.
Assume that sample data consists of 45 girls in 81 births, so the
sample statistic of 5/9 results in a z score that is 1 standard
deviation below 0. Complete parts (a) through (h) below.
a. Identify the null hypothesis and the
alternative hypothesis.
b. What is the...

answer all these questions please with the right question number

9-Test at the 0.01 level the statement that 55% (proportion) of
those families who plan to purchase a vacation residence in Florida
want a condominium. The null hypothesis is
π=.55 and the alternate is
π≠.55 .
A random sample of 400 families who planned to buy a vacation
residence revealed that 228 families want a condominium. Which of
the following are correct?
A
p=.57; the critical...

In this case ,Why do we use the left-tailed hypothesis instead
of the right-tailed hypothesis？When do we use the right-tailed
hypothesis and when do we use the left-tailed hypothesis? Explain
only the above two questions and do not need to answer the
following questions. Thanks!!
