Answer:
0.0139
Explanation:
Given that:
The number of sample (n) = 21
The sample distribution has mean (μ) and a standard deviation of σ/√n
The z score is given as (x - mean)/ standard deviation
x = 94.8 wpm, let us assume that σ = 10 and μ = 90
Therefore: z = (x - μ) / (σ/√n) = (94.8 - 90) / (10/√21) = 2.2
To calculate the probability using Z table:
P(X>94.8) = P(Z>94.8) = 1 - P(Z<94.8) = 1 - 0.9861 = 0.0139
The probability is low that is less than 0.05, the program is more effective than the old one.

Answer:
$434,000
Explanation:
Total machining cost = Number of machine hour * Rate per machine hour
= 3,100 * $140
= $434,000
Hence, The total machining cost allocated to product X is $434,000.
In classical conditioning, the Neutral Stimulus (NS) becomes a Conditioned Stimulus (CS) after it reliably signals the impending occurrence of the Unconditioned Stimulus (US).
The conditioned stimulus (CS) is a neutral stimulus (NS) that - after being repeatedly presented before the unconditioned stimulus - evokes a similar response as the unconditioned stimulus (US).
For example, a cat staring at a can of food (unconditioned stimulus) reacts differently to the sound of a can opener being struck on any surface (neutral stimulus). But if you condition a cat to believe that striking a can opener on any surface signals it will eat a can of food, the neutral stimulus becomes the conditioned stimulus.
