Answer:

t = 10.9

Step-by-step explanation:

9.3-t=-1.6

Subtract 9.3 from each side

9.3-t-9.3=-1.6-9.3

-t =-10.9

Multiply each side by -1 to find t

t = 10.9

The value of T is 10.9.

To find this, you must first get T on a side by itself. To do so, subtract 9.3 from both sides. This leaves -t = -10.9. Finally, divide both sides by -1, to make T positive. Thus meaning T = 10.9.

Consider a binomial distribution of 200 trials with expected value 80 and standard deviation of about 6.9. Use the criterion tha

mote1985 [20]

Answer:

The correct answer is option 'a' : 120 is more than 2.5 standard deviations above the expected value.

Step-by-step explanation:

For an exponential distribution we have

The expected value μ = 80

No of trails n = 200

Thus we have

$p=\frac{80}{200}=0.4$

The deviation is related to expected value and probability as

$\sigma =\sqrt{np(1-p)}\\\\\therefore \sigma =\sqrt{200\cdot 0.4\cdot (1-0.4)}=6.9$

Thus the values between the given deviation is

$x_{1}=80-2.5\times 6.9=62.75\\\\x_{2}=80+6.9\times 2.5=97.25$

Now since 120 successes are out of the range of [62.75,97.25] thus 120 is more than the expected value.

NARA [144]

To make a frequency table, you will need to find the lowest and highest average number of movies.

Numbers go from 0.5 to 4.5.
And example of frequencies you could use are:

0-0.9 (1)
1-1.9(5)
2-2.9(5)
3-3.9(2)
4-4.9(1)

The frequencies are in parentheses beside the intervals.
