Answer:
y=2.999973
Step-by-step explanation:
Let's solve your equation step-by-step.
Step 1: Simplify both sides of the equation.
Step 2: Subtract y from both sides.
Step 3: Divide both sides by 0.125001.
y=2.999973
Using the hypothesis test for one sample mean, There is NO SIGNIFICANT EVIDENCE to support the typist's claim

The test statistic :
T = (x - μ) ÷ (s/√(n))
T = (43 - 45) ÷ (15/√70)
T = - 2 ÷ 1.7928429
T = -1.1155
At α = 0.05
Pvalue :
Degree of freedom, df = 70 - 1 = 69
Pvalue = 0.134
Decison region :
Reject
if Pvalue < α
Since Pvalue > α We fail to reject the Null
