A recent study conducted by the state government attempts to determine whether the voting public supports a further increase in cigarette taxes to help the public schools. The opinion poll recently sampled 1500 voting age citizens. 622 of the sampled citizens were in favor of an increase in taxes. The state government would like to decide if there is enough evidence to establish whether the proportion of citizens supporting an increase in cigarette taxes is significantly greater than 66%. At what level of significance will the null hypothesis not be rejected?

_____ 24. State the null and alternative hypotheses. A study was
conducted to determine if there is a relationship between fan
preference of instant replay use and the sport in which it is
applied. The category counts of 102 fans are provided in the
two-way table below. Use a Chi-Square independence test to
determine if fan preference of instant replay use and the sport in
which it is applied are independent at the 5% level of
significance. State the null...

A study was conducted to determine whether the final grade of a
student in an introductory psychology course is linearly related to
his or her performance on the verbal ability test administered
before college entrance. The researchers hypothesized the linear
model y=β0+β1xy=β0+β1x, where xx is the score on the verbal ability
test and yy is the final grade in the psychology course. The verbal
scores and final grades for students are shown in the table
below.

A study was conducted to determine if a person’s
agreeability (whether they are generally an agreeable person or
not) affects their income level. It also looked at the person’s
gender to see if it was a factor as well. The variables are shown
below:
Income: y = annual income in
dollars
Agree: x1 = agreeability
level with higher scores indicating a person is more aggregable and
lower scores indicating less agreeable
Gender: x2 = 1 if male, 0 if
female...
