Marketers believe that 65.94% of adults in the U.S. own a cell phone. A cell phone manufacturer believes the proportion is different than 0.6594. 49 adults living in the U.S. are surveyed, of which, 37 report that they have a cell phone. Using a 0.10 level of significance test the claim. The correct hypotheses would be: О Но:р< 0.6594 HA:p > 0.6594 (claim) ОНо:р> 0.6594 HA:p < 0.6594 (claim) О Н:р — 0.6594 HA:p + 0.6594 (claim) Since the level of significance is 0.10 the critical value is 1.645 and -1.645 The test statistic is: (round to 3 places) The p-value is: (round to 3 places) The decision can be made to: O reject Ho O do not reject Ho The final conclusion is that: O There is enough evidence to reject the claim that the proportion is different than 0.6594. O There is not enough evidence to reject the claim that the proportion is different than 0.6594. O There is enough evidence to support the claim that the proportion is different than 0.6594. O There is not enough evidence to support the claim that the proportion is different than 0.6594.

A rescue claims that 30% of u.s. households have a dog. In a random sample of 210 u.s. households, 35% say they own a dog. Is there enough evidence to show the percentage has increased? Identify the appropriate null and alternative hypothesis. A) H0: p=0.35 vs Ha:p<0.35 B) H0: p=0.30 vs Ha:p>0.30 C) H0: p=0.30 vs Ha: p<0.30 D) H0: p=0.35 vs Ha:p>0.35
Consumer Reports stated that the mean time for a Chrysler Concorde to go from 0 to 60 miles per hour is 8.7 seconds. If you want to set up a statistical challenge to claim the average time from 0 to 60 miles per hour is less than 8.7 seconds, what would be the alternate hypothesis and type of test? a)H1: μ< 8.7, right-tailed test b)H1: μ>8.7, two-tailed test c) H1: μ<8.7,left-tailed test
An automotive company is conducting a survey concerning consumer buying preferences of a particular truck. The company wants to know whether the truck appearance, miles per gallon (MPG), or fixed price most influenced the consumer’s buying decision. A population sample of 500 individuals, both male and female, will be surveyed. State the null and alternative hypothesis if your were to test whether there is any difference in proportion using the three different criterion to purchase the given car based on gender.
A concerned group of citizens wanted to know if the proportion of armed robberies in Texas was different in 2011 than in 2010. Their research showed that of the 113,231 violent crimes in Texas in 2010, 7,622 of them were armed robberies. In 2011, 7,439 of the 104,873 violent crimes were in the armed robbery category. Test at a 5% significance level.a) The null and alternative hypothesis would be: �0:�2010=�2011�1:�2010≠�2011 �0:�2010=�2011�1:�2010<�2011 �0:�2010=�2011�1:�2010≠�2011 �0:�2010=�2011�1:�2010>�2011 �0:�2010=�2011�1:�2010>�2011 �0:�2010=�2011�1:�2010<�2011 b) Determine the test statistic.

A peony plant with red petals was crossed with another plant having streaky petals. A nursery owner states that 75% of the offspring resulting from this cross will have red flowers. To test this claim, 100 seeds from this cross were collected and germinated, and 67 plants had red petals. What hypotheses should you use to test the nursery owner's claim?

Past studies have indicated that the percentage of smokers was estimated to be about 34%. Given the new smoking cessation programs that have been implemented, you now believe that the percentage of smokers has reduced. You randomly surveyed 1807 people and found that 574 smoke.

O left-tailed O right-tailed O two-tailed c) Identify the appropriate significance level. d) Calculate your test statistic. Write the result below, and be sure to round your final answer to two decimal places. e) Calculate your p-value. Write the result below, and be sure to round your final answer to four decimal places. f) Do you reject the null hypothesis?

According to the national Center for health statistics, 74% of American women have been married by the age of 30. Suppose in a survey of 125 American women ( who are at least 30) and it is found that 91 of them were married at least once. Does the survey provide significant evidence that less than 74% of American women have been married by the age of 30? Test the relevant hypotheses at a significance level of 0.10.
