- Suppose you want to test the claim that a population mean equals 34. (a) State the null hypothesis. H0: μ > 34H0: μ < 34 H0: μ = 34H0: μ ≠ 34H0: μ ≥ 34 (b) State the alternate hypothesis if you have no information regarding how the population mean might differ from 34. H1: μ > 34H1: μ < 34 H1: μ = 34H1: μ ≠ 34H1: μ ≥ 34 (c) State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may exceed 34. H1: μ > 34H1: μ < 34 H1: μ = 34H1: μ ≠ 34H1: μ ≥ 34 (d) State the alternative hypothesis if you believe (based on experience or past studies) that the population mean may be less than 34.

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 testThe recidivism rate for convicted sex offenders is 13%. A warden suspects that this percent is different if the sex offender is also a drug addict. Of the 309 convicted sex offenders who were also drug addicts, 31 of them became repeat offenders.

- A biologist believes that there has been increase in the mean total suspended solids (TSS, mg/L) among Philippine rivers since its last study, where a mean 80 mg/L of TSS was observed. A random sample of 25 rivers was observed and the mean TSS was found to be 100 mg/L. Suppose it is of interest to test the biologist claim, the appropriate pair of null and alternative hypotheses is O Ho: µ-80, Ha: μ>80 O Ho: μ-100, Ha: µ>100 O Ho: X-bar = 80, Ha: X-bar > 80 O Ho: X-bar = 100, Ha: X-bar > 10017. A student did not believe their teacher when they stated that students tend to make more mistakes on their homework when listening to music.
