In order to conduct a hypothesis test for the population mean, a random sample of 20 observations is drawn from a normally distributed population. The resulting sample mean and sample standard deviation are calculated as 12.9 and 2.4, respectively. (You may find it useful to reference the appropriate table: z table or ttable). Ho : μ 12.1 against HA: μ > 12.1 a-1. Calculate the value of the test statistic. (Round all intermediate calculations to at least 4 decimal places...

In order to conduct a hypothesis test for the population mean, a random sample of 24 observations is drawn from a normally distributed population. The resulting sample mean and sample standard deviation are calculated as 6.3 and 2.5, respectively. (You may find it useful to reference the appropriate table: z table or t table). H0: μ ≤ 5.1 against HA: μ > 5.1 a-1. Calculate the value of the test statistic. (Round all intermediate calculations to at least 4 decimal...

manufacturer is interested in the output voltage of a power supply used in a PC. Output voltage is assumed to be normally distributed, with standard deviation 0.36 volt, and the manufacturer wishes to test Ho:μ= 5 volts against H1:μ#5 volts, using n-9 units. Round your answers to four decimal places (e.g. 98.7654) a) The acceptance region is b) Find the power of the test for detecting a true mean output voltage of 5.1 volts 4.81 ヌ 5, 11 . Find...

In order to conduct a hypothesis test for the population mean, a random sample of 28 observations is drawn from a normally distributed population. The resulting sample mean and sample standard deviation are calculated as 17.9 and 1.5, respectively. (You may find it useful to reference the appropriate table: z table or t table) H0 : μ 17.5 against HA: μ > 17.5 a-1. Calculate the value of the test statistic. (Round all intermediate calculations to at least 4 decimal...
