Nine less than three times a number is greater than forty
pentagon [3]
Start with an equation.
Nine less... so -9
3 times a number = 3x
Greater than 40 is >40

So put together is 3x-9>40
When solving I imaging the greater than sign as an equal sign. Less confusing.
3x-9=40
3x=49
x>49/3

The average response time to a bank robbery is 9 minutes. A local community wants to improve on this time, so they implement adv
timurjin [86]

Answer:

The training does reduce response time at 0.05 level of significance

Step-by-step explanation:

Population mean for a population with normal distribution, where the standard deviation is known and the appropriate significant test is given then;

z=x-μ / δ/√n

where

μ= 9 minutes

x=8 minutes

δ= 4.2

n= 36

Applying the formula;

z= 8-9 / 4.2/√36

z= -1 / 4.2/6

z= -1 /0.7 = - 1.429

Perform the test where

H₀ : p=0.05 verse Ha : p < 0.05

Using the Z-table, find the probability that Z is less than -1.43.

You will find the probability of 0.0764 of Z being more than the value in test thus; there are high chances that results will be observed according to the null hypothesis
