Answer:
14n^2.
Step-by-step explanation:
This is Arithmetic with first term a = 14 and common difference d = 28.
Sum of n terms = n/2[2a + (n-1)d]
= n/2(28 +( n -1)28]
= n/2(28 + 28n - 28)
= 14n^2
Answer: t _(α/2) = 2.060
Step-by-step explanation:
Given that;
sample size n = 26
confidence interval = 95%
level of significance α = ( 1 - 95/100 ) = 0.05
but from the question the salaries (26) are use to estimate the mean of the population so, its a two tail test
therefore our level if significance α will be divided by 2 = 0.05/2 = 0.025
now our degree of freedom df = 26 - 1 = 25
FROM standard t-table value
the critical value of t for the level of significance 0.025
and 25 degree of freedom is 2.060
therefore, t _(α/2) = 2.060
Answer: 6.62 weeks
Step-by-step explanation:
Time taken by Ryan to build a home = 13.4 weeks
Time taken by Jack to build the same home = 13.1 weeks
