- In a recent Super Bowl, a TV network predicted that 59 % of the audience would express an interest in seeing one of its forthcoming television shows. The network ran commercials for these shows during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 80 people who saw the commercials and found that 48 of them said they would watch one of the television shows. Suppose you are have the following null and alternative hypotheses for a test you are running: Ho: p = 0.59 Ha: p0.59 Calculate the test statistic, rounded to 3 decimal places Z Submit Question2. To test whether memory changes with age, a researcher conducts an experiment in which there are four groups of six subjects each The groups differ according to the age of subjects. Each subject is shown a series of nonsense syllables. The subject is then asked to free recall the syllables. The number of syllables remembered by each subject is shown below. ever 30 years old 14 40 years old 12 50 years old 17 60 years old 13 15 14 10 13 erd 15 16 14 7 17 11 8 12 12 13 6. 10 18 15State the null and alternative hypotheses of the following statements (in words). 5. According to the 2010 Census, 16% of the people in the United States are of Hispanic or Latino origin. One county supervisor believes her county has a different proportion of Hispanic people than the nation as a whole. Using mathematical notation, identify ber claim, the null hypothesis and the alternative hypothesis. Question 1 is continued on the next page 6. In 1960, census results indicated that the age at which American men first married had a mean of 23.3 years. It is widely suspected that young people today are waiting until they are older to get married. Using mathematical notation, identify this claim, the null hypothesis and the alternative hypothesis 7. Because color television did not become common until 1965, the claim is that more people over 60 dream in black and white than people who are under 50 do. Using mathematical notation, identify the claim., the null hypothesis and…
- The recidivism rate for convicted sex offenders is 15%. A warden suspects that this percent is different if the sex offender is also a drug addict. Of the 329 convicted sex offenders who were also drug addicts, 43 of them became repeat offenders. What can be concluded at the α = 0.10 level of significance?

The data suggest the populaton proportion is significantly higher than 13% at α = 0.10, so there is statistically significant evidence to conclude that the the percentage of all registered voters who will vote in the upcoming election will be higher than 13%.

Answer the following questions for a hypothesis test that could be used to test the claim on the label. (a) Develop the appropriate null and alternative hypotheses. H0: ? > 1 Ha: ? ≤ 1 H0: ? < 1 Ha: ? ≥ 1 H0: ? ≤ 1 Ha: ? > 1 H0: ? = 1 Ha: ? ≠ 1 H0: ? ≥ 1 Ha: ? < 1 (b) What is the type I error in this situation? What are the consequences of making this error? It is claiming ? < 1 when it is not. This error would claim that the product is not meeting its label specification when it really is meeting its specification. It is claiming ? ≥ 1 when it is not. This error would miss the fact that the product is not meeting its label specification. It is claiming ? ≤ 1 when it is not. This error would miss the fact that the product is not meeting its label specification. It is claiming ? > 1 when it is not. This error would claim that the…
