Answer:
Paired difference t test
Step-by-step explanation:
The paired difference t test is a type of statistical test which is used to examine if difference exists in th population mean of two samples. The paired difference test usually involves samples taken within subjects. That is, the sample mean for each set of measurement is taken from the Same subject, In the scenario described above, the subjects which are the 6 veteran runners each wore each of the two shoe brands, this means that two readings were produced by each runner ; one reading for brand A and the other brand B.
The difference between the two readings are taken for each runner and used to perform a hypothesis test:
t = μd/ (s/√n)
s = sample standard deviation ; n = sample size ; μd = mean difference

Answer:
$22350 is the predicted value of portfolio.
Step-by-step explanation:
The given expression is 1.08s + 1.02b1.08s + 1.02b which predicts the end of year value of a financial portfolio.Here s = value of stocks and b = value of bonds.
Now we have to calculate the value of a portfolio with s = $200 and b = $100
So we will put the values of s and b in the given expression to calculate the value portfolio.
1.08×200 +1.02×(100)×1.08×(200)+ 1.02×(100) = 216 + 22032 + 102
= $22350
The predicted end to end year value of portfolio is = $22350
Answer:
