A random sample of n1 = 262 people who live in a city were selected and 117 identified as a "dog person." A random sample of n2 = 108 people who live in a rural area were selected and 55 identified as a "dog person." Find the 90% confidence interval for the difference in the proportion of people that live in a city who identify as a "dog person" and the proportion of people that live in a rural area who identify as a "dog person."

Ten car drivers were asked to parallel park 2 cars having very different wheel bases and turning radii. The time in seconds for each driver was recorded. The 90% confidence interval for the mean differences is [-2, 5]. This implies that, at the 90% level of confidence, the data do not support the claim that the two cars have different mean parking times. True or False?

A large school district found that 88 of 100 randomly selected students at East High School had internet access at home . A separate random sample from West High showed 79 of 100 students had internet access at home Administrators used those results to make a 90\% confidence interval to estimate the difference between the proportion of students at each school who have internet access at home (p Z -p W ) . resulting Interval was approximately 0.09 plus/minus 0.086 . They want to this interval to test H 0 * p 0 =p w versus H k :p k ne pw at the alpha = 0.10sisnl significance levelAssume that all conditions for Inferance been mel Based on the Intervalwhat do we know about the corresponding P-value and condusion at the alpha = 0.10 level of significance?
Data were collected from a study that followed 1,490 Australian married couples for three years to learn what factors may lead to marital separation or divorce. During the study period, 42 of 971couples in which neither partner smoked separated. Among 519 couples in which at least one partner smoked, 70 couples separated.

PT. “ABC” in 2018 offers a new portfolio for investment. For this new product, companies need to know the ability of investors to face risk. For this purpose, samples were taken from two groups, namely the old and young groups, each of which was taken as many as 160 old and young investors. The survey results showed that as many as 90 older people and 70 young people agreed to accept greater risk. Make a confidence interval for the difference in the proportion of the ability to face the risk.
