- In a hypothesis test, a Type l| error occurs when: O 1) a false null hypothesis is rejected O 2) a true null hypothesis is not rejected 3) a false null hypothesis is not rejected O 4) a true null hypothesis is rejectedAccording to a study, approximately 60% of US adults believe that they have achieved, or are within reach of, the "American Dream" (that is, home ownership and financial stability). Now consider a random sample of 400 US adults. What is the probablity that over 65% of the sampled adults believe they have reached or are optimistic about reaching the American Dream? NEED ANSWER! No explanattion pleaseThe claim is that the proportion of adults who smoked a cigarette in a past week is less than 0.25, and the sample statistics include n = 1018 subjects with 224 saying that they smoked a cigarette in the past week. A) Find the null hypothesis and alternative hypothesis in symbolic form. B) Find the test statistics using the formula.
- Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 484 were in favor, 397 were opposed, and 123 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 123 subjects who said that they were unsure, and use a 0.10 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim? Identify the null and alternative hypotheses for this test. Choose the correct answer below. А. Но: р3D0.5 H4:p>0.5 В.

The scientist, believing that u is different from this value, plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7.9 pounds and the standard deviation to be 1.6 pounds. Based on this information, answer the questions below.6.
