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:
the answer is b
Step-by-step explanation:
New value =
29,000 + Percentage increase =
29,000 + (- 5% × 29,000) =
29,000 - 5% × 29,000 =
(1 - 5%) × 29,000 =
(100% - 5%) × 29,000 =
95% × 29,000 =
95 ÷ 100 × 29,000 =
95 × 29,000 ÷ 100 =
2,755,000 ÷ 100 =
27,550
