Since the sample size is below 30, in this case we use
the t statistic. The formula for t score is:
t = (x – u) / (σ / sqrt n)
where,
x = the level l = unknown
u = sample mean = 120 mg / dl
σ = standard deviation = 20 mg / dl
n = sample size or number of results = 5
Using the standard distribution tables for t, we can find
the value of t given the probability (P = 0.15) and degrees of freedom (DOF).
t = 1.036
Going back to the
formula for t score:
1.036 = (x – 120)
/ (20 / sqrt 5)
x = 129.27 mg /
dl = l

When Benedict's reagent is <span>mixed and heated with glucose and galactos, the copper accept the electrons and become reduced. </span><span>Benedict's test detects the presence of </span><span>aldehydes in solution.</span>
Answer: 169ml
Explanation
At constant temperature, PV is constant
Standard pressure is 101 kpa
150ml X 114kpa=?mlX101 kpa
?=114/101 X150 = 169 ml
