In a certain school district, it was observed that 24% of the students in the elementary schools were classified as only children (no siblings). However, in the special program for talented and gifted children, 56 out of 193 students are only children. The school district administrators want to know if the proportion of only children in the special program is significantly different from the proportion for the school district. Test at the a = 0.05 level of significance. What is the hypothesized population proportion for this test? p = | .24 (Report answer as a decimal accurate to 2 decimal places.

A study of sleepwalking or "nocturnal wandering" was described in the journal Neurology, and it included information that 29.2% of 19,136 American adults have sleepwalked. Would a reporter be justified in stating that "fewer than 30% of adults have sleepwalked"? Let's use a 0.05 significance level to test the claim that for the adult population, the proportion of those who have sleepwalked is less than 0.30. Question: In symbols, what is the claim? O p=0.3 O p0.3 p>0.292 O p=0.292 p
In a certain school district, it was observed that 30% of the students in the element schools were classified as only children (no siblings). However, in the special program for talented and gifted children, 107 out of 295 students are only children. The school district administrators want to know if the proportion of only children in the special program is significantly different from the proportion for the school district.

Consider a drug testing company that provides a test for marijuana usage. Among 349 tested subjects, results from 26 subjects were wrong (either a false positive or a false negative). Use a 0.01 significance level to test the claim that less than 10 percent of the test results are wrong.
A recent report from the Pew Research Center indicates that even teens think they have a problem being too attached to their phones. A total of 365 teenage girls and 378 teenage boys were surveyed. Of the teenage girls surveyed, 171 reported feeling too attached to their phone. Of the teenage boys surveyed, 132 reported feeling too attached to their phone. Is there convincing statistical evidence of a difference between the two population proportions at the significance level of 0.01? (A) Yes, because the sample proportions are different. (B) Yes, because the p-value is less than 0.01. (C) Yes, because the p-value is greater than 0.01. (D) No, because the p-value is less than 0.01. (E) No, because the p-value is greater than 0.01.

Consider a drug testing company that provides a test for marijuana usage. Among 253 tested subjects, results from 25 subjects were wrong (either a false positive or a false negative). Use a 0.01 significance level to test the claim that less than 10 percent of the test results are wrong.
Astudy was conducted to determine the proportion of people who dream in black and white instead of color. Among 317 people over the age of 55, 63 dream in black and white, and among 300 people under the age of 25, 17 dream in black and white. Use a 0.01 significance level to test the claim that the proportion of people over 55 who dreamn tackand white is greater than the proportion for those under 25. Complete parts (a) through (c) below. a. Test the claim using a hypothesis test. Consider the first sample to be the sample of people over the age of 55 and the second sample to be the sample of people under the age of 25.

USA Today ran a report about a UNC poll of 1248 adults from the southern U.S. It was reported that 8% of those surveyed believe that Elvis Presley still lives. The article began with the claim that "almost 1 out of 10" Southerners still thinks Elvis is alive. At the 0.01 significance level, test the claim that the true percentage is 10%.
A survey of 1031 adults in a college asked whether they liked chocolate or strawberry ice cream more. Of those surveyed, 536 said they prefer chocolate. Determine and interpret the sample proportion. At the 5% significance level, does the data provide sufficient evidence to conclude that a majority of students in the college prefer chocolate ice cream?
