Step-by-step explanation:
Answer:
a) The mean is 0.15 and the standard error is 0.056.
b) 1. Yes
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For proportions p, in samples of size n, the mean is and the standard error is . The Central Limit Theorem applies is np > 5 and np(1-p)>5.
In this question:
So
(a) Find the mean and the standard error of the distribution of sample proportions.
So the mean is 0.15 and the standard error is 0.056.
(b) Is the sample size large enough for the Central Limit Theorem to apply?
np = 40*0.15 = 6 > 5
np(1-p) = 40*0.15*0.85 = 5.1>5
So yes
Answer:
the answer is c for Friday and 6 3/12 hours for them both combined
Step-by-step explanation:
because 3 5/12 is closest to 3 1/2=3 6/12
for fir day and Saturday day combined it would be 6 3/12
because 5/6 is 10/12 and 5/12 + 10/12 is 15/12 which is also 1 3/12
so add 3 +2=5 and then add the fraction 1 3/12 which would be 6 3/12 hours
Answer:
circumference of circle = 2π×r
here r = 7
so 2 ×22÷7 × 7
= 2×22
= 44
therefore the circumference is 44 inches
Here is how we are going to get the answer. Given that the maturity value of a $16,000 <span>non-interest-bearing, simple discount 6%, the 60-day note would be this: 16,000 x 0.06 x 60/360 = x
960 x 60/360 = x
960 x 0.17 = x
x = 163.2
So the answer for this would be $163.20. Hope this answers your question.</span>
