Answer:
The probability is
Step-by-step explanation:
From the question we are told
The population proportion is
The sample size is
The number of graduate who had job is k = 209
Generally given that the sample size is large enough (i.e n > 30) then the mean of this sampling distribution is
Generally the standard deviation of this sampling distribution is
=>
=>
Generally the sample proportion is mathematically represented as
=>
=>
Generally probability of obtaining a sample proportion as low as or lower than this, if the university’s claim is true, is mathematically represented as
From the z table the area under the normal curve to the left corresponding to -3.022 is
=>
Answer:
$2000
Step-by-step explanation:
The formula for simple interest is:
Where
i is the interest earned
P is the initial deposit
r is the rate of interest (in decimal)
t is the time
Now, in the problem, it is given:
i = 480
r = 4% = 4/100 = 0.04
t = 6
Now, we substitute and find the value of P (initial deposit):
Hence, the initial deposit was $2000
