Debate has emerged and raged on regarding many African countries including Ghana not making rapid economic progress in an emerging knowledge economy. Poverty exists in spite of development being driven by technology, fuelled by information and powered by knowledge, and, many are oblivious to the reality that information and communication technology (ICT) cuts across all aspects of our lives.
We take a queue from the ICT driven economic experiences of the United States during the dot com boom and developments in Finland and other Western economies. We are informed by issues of globalization, the knowledge economy and the transformation of business processes using ICT in India, China, Korea and Malaysia. Close to us in Africa we are encouraged by economic growth using ICT in Rwanda and South Africa.
Pundits have argued that illiteracy is to be blamed, and mathematics and science education needs to be prioritized. Others say it is in our attitude fashioned by our past which does not relate development as an independent variable relative to other variables such as technology. While some view our challenges as lack of leadership to implement sustainable ICT policies and strategies at a macro and micro level, many argue that development of a nation’s economy has much to do with input from ICT personnel. They do not only belong to the domain of personnel with tacit knowledge of engineers who should provide infrastructure but such need to study policies that determine development

ii. What software option will you recommend to your ministry? Open source or Microsoft as proprietary software? Provide reasons for your recommendation.
iii. List FIVE (5) ways of how the TPS can be of use to a government department.

Step b: Create a new dataframe df which is the summation of df1 and df2;

Step c: Subtract all columns of df by the half of column 'C' in df1; (Remark: the values in df should be updated)

Step d: Replace the NaN in df by 10; (Remark: the values in df should be updated)

PH experiment:

What is one real-world or practical application for this experiment or portion of this experiment?

Define the following: abscissa, acid, base, endpoint, equivalence point, neutralization, pH, pKa, mono- protic acid, polyprotic acid, ordinate, strong acid, strong base, and weak acid.

Draw the structure of each of the acids in Table 1.

Produce data tables for each of your runs. Leave room in your notebook for lots of data. Record the actual volume of titrant and solution pH as you conduct the experiment.

Identify all potentially hazardous steps in your procedure. In your own words, explain what safety precautions should be taken and why.

Consider the titration of 0.050 M HCl with 0.050 M NaOH. Calculate the pH: (a) of the pure HCl solution; (b) of 25.00 mL acid plus 12.50 mL base; (c) at the equivalence point; and (d) of 25.00 mL acid and 37.50 mL base.

Suppose, household color TVs are replaced at an average age of μ = 8.4 years after purchase, and the (95% of data) range was from 5.0 to 11.8 years. Thus, the range was 11.8 – 5.0 = 6.8 years. Let x be the age (in years) at which a color TV is replaced. Assume that x has a distribution that is approximately normal. (a) The empirical rule indicates that for a symmetrical and bell-shaped distribution, approximately 95% of the data lies within two standard deviations of the mean. Therefore, a 95% range of data values extending from μ – 2σ to μ + 2σ is often used for "commonly occurring" data values. Note that the interval from μ – 2σ to μ + 2σ is 4σ in length. This leads to a "rule of thumb" for estimating the standard deviation from a 95% range of data values. Estimating the standard deviation For a symmetric, bell-shaped distribution, standard deviation ≈ range 4 ≈ high value – low value 4 where it is estimated that about 95% of the commonly occurring data values fall into this range. Use this "rule of thumb" to approximate the standard deviation of x values, where x is the age (in years) at which a color TV is replaced. (Round your answer to one decimal place.) yrs (b) What is the probability that someone will keep a color TV more than 5 years before replacement? (Round your answer to four decimal places.) (c) What is the probability that someone will keep a color TV fewer than 10 years before replacement? (Round your answer to four decimal places.) (d) Assume that the average life of a color TV is 8.4 years with a standard deviation of 1.7 years before it breaks. Suppose that a company guarantees color TVs and will replace a TV that breaks while under guarantee with a new one. However, the company does not want to replace more than 6% of the TVs under guarantee. For how long should the guarantee be made (rounded to the nearest tenth of a year)? yrs
