The constant of proportionality is: 0.2 and the equation is: c = 0.2t
Step-by-step explanation:
Let t be the number of texts and c be the cost
Then according to given statement
c ∝ t
The proportionality symbol will be removed and a constant f proportionality will be introduced.
<u>For constant of proportionality:</u>

Answer:
Hello your question has some missing part below is the missing part
The mean hours per week and standard deviations for middle management who had been with the organizations for approximately the same length of time were: Baltimore facility, Burlington facility Mean 52.5 Mean 39.7
Standard deviation 19.7 Standard Deviation 8.9Using this data, complete the following:
State your hypothesis and conduct a hypothesis testing using a significance of 0.10.
answer : We will reject the Null hypothesis
Step-by-step explanation:
μ1 = mean working hours for Baltimore facility
μ2 = mean working hours for Burlington facility
Hence the Hypothesis are :
H0 : μ1 = μ2
Ha : μ1 > μ2
<em>Next: Conduct a hypothesis testing </em>
we will apply Z - testing attached below is the hypothesis testing
n1 = 145 , X1 = 52.5 , δ1 = 19.7 ( Baltimore )
n2 = 128, X2 = 39.7 , δ2 = 8.9 ( Burlington )
