null Hypothesis:               Ho:   p = 0.800
alternate Hypothesis:    Ha: p > 0.800
for 0.05 level with right tailed test , critical z= 1.645 #(use normsinv(0.95) function of excel)
Decision rule :   reject Ho if test statistic z > 1.645
sample success x   = 95
sample size          n    = 115
std error   se =√(p*(1-p)/n) = sqrt(0.8*0.2/115)= 0.0373
sample proportion p̂ = x/n=95/115= 0.8261
test stat z =(p̂-p)/√(p(1-p)/n)=(0.8261-0.80)/0.0373= 0.700
p value                          = 0.2420 # use 1-normsdist(0.70) function of excel(

since p value is greater than 0.05 level, we fail to reject null hypothesis

we do not have sufficient evidence at 0.05 level to conclude that percentage of investors who are risk–taking (i.e., trying to take risk in their investment decisions) is greater than 80%.

Coupon payments are fixed, but the percentage return that investors receive varies based on market conditions. This percentage returned is referred to as a yield. A bond’s yield to maturity (YTM) is the percentage return that it is expected to generate if the bond is assumed to be held until it matures. Calculating a bond’s YTM requires you to make several assumptions. Which of the following is one of these assumptions? The bond is callable. The probability of default is...
