Answer:
69.86 slugs
Explanation:
From the ideal gas equation
PV = nRT
n (number of moles) = PV/RT
P is pressure of the gas = 30 atm = 30×101325 = 3,039,750 Pa
V is volume of the gas = 1000 ft^3 = 1000/3.2808^3 = 28.32 m^3
R is gas constant = 8.314 J/mol.K
T is the temperature of the gas = 530 R = 5/9 × 530 = 294.44 K
n = 3,039,750×28.32/8.314×294.44 = 35166.11 mol
mass = n× MW
MW of air = 29 g/mol
mass = 35166.11 × 29 = 1019817.19 g × 0.0685 slug/1000 g = 69.86 slugs

Answer
Procedural bias occurs when the unfair amount of pressure is applied to complete their response quickly.
Measurement bias occurs when there is systematic or random error occur while taking the reading.
Design bias occur when the research fails to encounter all the aspects of the projects before presenting conclusion.
1) The correct answer is option B.
Balance is miscalibrated hence there will be systematic error which is a type of measurement bias.
2) The correct answer is option A.
Limiting response time for participant is an example of Procedural bias.
3) The correct answer is option A
Here, Jackie has not surveyed the diverse group so it is the case of design bias
