Percent of change = (Amount of Change) / (Original Amount)
Percent of change = (375 - 350) / 350
= 25 / 350
= 1 / 14
= approximately 7.14%
So the employer is going to need at least a 7.14% increase.

Step-by-step explanation:
Answer:
B) TS = -6.51, p-value = 0.0000
Step-by-step explanation:
Sample size, n = 39
μ = 7.5 cm
Null hypothesis, H₀ = 7.5 cm
(I.e. Average height of youngest child is 7.5 cm)
Alternative hypothesis,
(The youngest child's age is underestimated by 7.5 cm)
Standard deviation, 
In order to be able to reject the null hypothesis,
the formula for the test statistic:


t = -6.51
P - value
P(x < 7.5) = P(z < -6.51)
Checking the p-value for z < -6.51 in the normal distribution table
P(z < -6.51) = 0.0000
p - value = 0.0000
