Let's discuss the disadvantage of CFCs and how it will affect
our global environment. What are substitute refrigerants used to
replace the CFCs in the Refrigeration system?
“Singleton design pattern provides stricter control over
global
variables.”
Justify this statement with your own logic.
Compare Singleton design pattern and global variable (similarities
and differences)
Implement any example (in JAVA), representing concept of global
variable and Singleton design
pattern, highlight the differences with coding and output.
Our environment is very sensitive to the amount of ozone in the
upper atmosphere. The level of ozone normally found is 4.14.1
parts/million (ppm). A researcher believes that the current ozone
level is at an insufficient level. The mean of 10401040 samples is
4.04.0 ppm. Assume a population standard deviation of 1.21.2. Does
the data support the researcher's claim at the 0.020.02 level?
Step 1 of 6: State the null and alternative hypotheses.
Step 2 of 6: Find the value...
Our environment is very sensitive to the amount of ozone in the
upper atmosphere. The level of ozone normally found is 5.5
parts/million (ppm). A researcher believes that the current ozone
level is not at the normal level. The mean of 13 samples is 6.0 ppm
with a standard deviation of 0.9 Does the data support the claim at
the 0.1level? Assume the population distribution is approximately
normal.
Step 1 of 3 : State the null and alternative
hypotheses.
