Answer:
Sample size is 16
Mean 4
Standard deviation of the sample is 0.3.
Explanation
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation 
.
In this problem, we have that:
The population has a mean of four hours, with a standard deviation of 1.2 hours. The sample is the 16 of the employees.
So
The sample size is 16, so 
The mean of the sample is the same as the population mean, so 
.
The standard deviation of the sample is 
Answer:
Approximately $37000
Explanation:
A standard normal curve will be used to solve this question since the histogram of the data takes on a mound shape.
The mean salary is $33000 with one standard deviation equalling $2000.
Using the normal curve, 95% of the salary will lie between 2 standard deviation. i.e. $33000+$2000+$2000=$37000
Answer:
Using predetermined totals to control posting routines.
Explanation:
A validation methods to avoid errors is the batch total control, that verificate the transcription errors and transportation errors.
Validations aims to make sure that data is sensible, reasonable, complete and within acceptable boundaries.
The batch total checks that something is not missing by adding together a number field in different records and checking the total. For example, if an invoice has three items costing 1,2 and 3, the control will look for a batch total of 6.
Answer:
One of the key aspects of choosing the best career is by thinking about yourself. Many people in your life can tell you what you should do, or what they think you’d be good at, but the only person who truly knows which career is best, is yourself.
Start by thinking about your passions and what you’re interested in. If you have a love for writing, a career in construction, for example, may not be the best fit. Instead, you’d look at more creative fields such as journalism, copywriting or even creative writing. Knowing and discovering what you enjoy and feel passionate about will give you a strong start to discovering a career path for you.
