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

Answer:
Stacy's middle school
Step-by-step explanation:
356 divided by 38 = 9
219 divided by 28 = 7
Each angle has a sin, cos, and tan associated with it.
in a right angled triangle there are two other angles which each have ratios.
3/4+z=5/6
Find the common denominator which is 12 for 3/4 and 5/6.
Multiply by 3 for 3/4.
Multiply by 2 for 5/6.
3(3)/4(3)=9/12
5(2)/6(2)=10/12
9/12+z=10/12
Move 9/12 to the other side. Sign changes from 9/12 to -9/12.
9/12-9/12+z=10/12-9/12
z=1/12
Answer: z= 1/12
Find the amount of change by subtracting the two quantities. Divide this number by the original (starting) quantity, and convert to percent form by moving the decimal 2 places to the right.
