Question;YOUR FULL NAME: Answer Optional for Partial Credit1. [6 pts.] We have evidence to believe that variances are equal (True/False):F = p-value = 2. [12 pts.] a. Eq. vars? = Uneq. vars numerator = Uneq. vars? = Uneq. vars denominator = b. Eq. vars? = Uneq. vars numerator = Uneq. vars? = Uneq. vars denominator = c. Eq. vars? = Uneq. vars numerator = Uneq. vars? = Uneq. vars denominator = d. Eq. vars? = Uneq. vars numerator = Uneq. vars? = Uneq. vars denominator =?3. [12 pts.] The manager should hire a security guard (TRUE or FALSE):Equal variances: F = p-value = Variances are equal (True/False): Two-Sample Test: t= p-value= 4. [12 pts.] Americans are more deeply in debt this year (True or False):This is a right-tailed t-test (True or False): Hypothesized Mean Difference: t= p-value= 5. [18 pts.] a. p-value= x1 = x2 = p? = Numerator of z = Denominator of z = z = this is a two-tailed test (TRUE or FALSE): b. p-value= x1 = x2 = p? = Numerator of z = Denominator of z = z = this is a two-tailed test (TRUE or FALSE): c. p-value decreases because standard error decreases as sample sizes increase (TRUE or FALSE)
