To test Upper H0: muμequals=60 versus Upper H1: muμless than<60, a random sample of size n=24 is obtained from a population that is known to be normally distributed. Complete parts (a) through (d) below. Click here to view the t-Distribution Area in Right Tail. (a) If x overbar x=57.5 and s=12.5 compute the test statistic. t 0=nothing (Round to three decimal places as needed.) (b) If the researcher decides to test this hypothesis at the a=0.05 level of significance, determine the critical value(s). Although technology or a t-distribution table can be used to find the critical value, in this problem use the t-distribution table given. Critical Value: nothing (Round to three decimal places.

o test H0: μ=40 versus H1: μ<40, a random sample of size n=25 is obtained from a population that is known to be normally distributed. If x=37.1 and s=14.8, compute the test statistic of t0 and If the researcher decides to test this hypothesis at the α=0.1 level of significance, determine the critical value.
The random variable x represents the reaction times, in milliseconds, of girls in adriving simulator. x is Normally distributed with mean 355 and standard deviation52.(a) Using Excel or otherwise, calculate(i) P (x < 325) (ii) P(300 < x < 400) (b) Using Excel or otherwise, find the value of k such that P(x < ?) = 0.3
A researcher is testing a null hypothesis that states, H0: μ= 50. A sample of 25 scores is selected and M= 55. Assuming the sample variance is s2 = 100, compute the estimated standard error and the t-statistic. Is this sample sufficient to reject the null hypothesis using a two-tailed test with a= .05? Note: This is a two-tailed test HA: df= tα or t value for the critical region = sM = t = Decision
A chi-squared random variable with ν > 0 degrees of freedom (χv2) has mgf M(t) = (1 − 2t) −ν/2 . Given that Z2 ∼ χ21, derive the mean and variance of Z2 using M(t). Confirm these results using the mgf of Z, namely MZ(t) = e1/2t2 .
