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

The percentages from the different samples will have a true population percentage mean.
A real population proportion shows the percentage of a population that exhibits a particular trait.
A population's proportions will have a real population proportion mean if numerous big random samples or repeats of the same size are taken.
Here is an illustration of how to cross multiply, or find a cross product. In this instance, you multiply 3 x 10 to get 30 and then 5 x 6 to get 30. The proportion is accurate because the two products are equal.

Answer:
Account A = $ 96.80
Account B = $ 48.40
Step-by-step explanation:
Account A
Principal = $1,000
rate = 2.42% = 0.0242
time = 4 years
To find the interest we will use the formula :
I = PTR
I = 1000 x 4 x 0.0242
I = $96.80
Account B
P = 1,000
t = 24 months = 2 years
r = 2.42% = 0.0242
I = PTR
I = 1000 x 2 x 0.0242
I = $ 48. 40
difference in interest = Interest a - Interest b
difference = 96.80 - 48.40
difference = $ 48 . 40
The interest on Account A doubles the interest on Account B
Answer:
0.35
Step-by-step explanation:
P(0) = 348/1000
0.348
0.35 to the nearest hundredth
