In a UK survey of a random sample of 281 working women who had children, 175 reported that they felt that having children had held back their career prospects. In a similar study of 138 women in Denmark, 65 reported that having children had held back their career.
(a) Produce a 95% confidence interval for the proportion of women in the UK who consider that having children held back their career prospects.
(b) Produce a 95% confidence interval for the proportion of women in Denmark who consider that having children held back their career prospects.
(c) How do the two confidence intervals compare?
Propane at 343.15 K (70°C) and 101.33 kPa is compressed isothermally to 1500 kPa. Estimate AH and AS for the process by suitable generalized correlations.
What is the magnitude of the signal, in volts, that you could expect from the microphone? Assume that we get a maximum signal when the flux varies from 0 to the value of Φ calculated in Part B. (Assume that sound has a frequency of order 500Hz.)Volta..
The liquid-phase irreversible reaction A ? B is carried out in a CSTR. To learn the rate law, the residence time, t is varied and the effluent concentrations of species A are measured.
Assuming the solution has a heat capacity of 4.18 J/C g and assuming no heat loss to the calorimeter, calculate the enthalpy change for the dissolution of NH4NO3 in units of kJ/mol.
Calculate the energy required to raise the temperature of 1.0 mol Ag by 1.0C (called the molar heat capacity of silver). c. It takes 1.25 kJ of energy to heat a sample of pure silver from 12.0C to 15.2C. Calculate the mass of the sample of silv..
The maximum possible purity of glycol in the finished extract and the maximum purity of water in the raffinate for one equilibriumstage.
with an atomic weight of 51.9405 amu, 9.50% of 53Cr, with an atomic weight of 52.9407 amu, and 2.37% of 54Cr, with an atomic weight of 53.9389 amu. On the basis of these data, confirm that the average atomic weight of Cr is 51.9963 amu.
The product, acetone, is sent to storage and the waste to an effluent pond. It is essential that the specifications on product and waste quality are met.
The precipitate was collected, dried, and found to weigh 1.36 g. Determine the atomic mass of M, and identify M.
