A normal distribution is a type of continuous probability distribution for a real-valued random variable in statistics.

Yes, the large-sample confidence interval will be valid.

<h3>What is meant by normal distribution?</h3>

A normal distribution is a type of continuous probability distribution for a real-valued random variable in statistics.

The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data far from the mean.

The confidence interval will be valid regardless of the shape of the population distribution as long as the sample is large enough to satisfy the central limit theorem.

<h3>What does a large sample confidence interval for  a population mean?</h3>

A sample is considered large when n ≥ 30.

By 'valid', it means that the confidence interval procedure has a 95% chance of producing an interval that contains the population parameter.

What is the value of 5k2−6 when k = 9?
Anarel [89]

Answer:

84

Step-by-step explanation:

Plug in 9 for k.

5(9)(2) - 6

first: (9)(2) = 9 x 2 = 18

5(18) - 6

second: 5(18) = 5 x 18 = 90

last: 90 - 6 = ?

84

Y= ∛(-x) - 3
for x = -8 → y = ∛-(-8) - 3 ↔ y = 2-3 ↔y = -1
for x= 8 → y= ∛(-8) - 3 ↔ y = -2 -3 ↔ y = -5
Then  - 5≤ y≤ - 1
hence the range of y is {y|-5≤y≤-1}

Is the relationship linear, exponential, or neither?
kati45 [8]

Answer:

Neither linear nor exponential

Step-by-step explanation:

To check for a linear relationship.  Find slope.

slope=  (-1  -  (-2)) / ( 5 - 2)  = 1/3

check  other points

slope = (1 - (-1) )/ (8 - 5) =  2/3

check more

slope = (4 - 1) / (11 - 8) = 3/ 3 = 1

Nope.

try assuming an exponential:

y = c * (a^x)

-2 =  c* (a^2);    -2/c = a^2

-1 = c *(a ^5);    -1/c = a^5

1 =  c * (a^8),     1/c = a^8

(-2/c)^4 = a^8 = 1/c

16/(c^4) = 1/c

c^3 = 16,  then    a = root (-2/ cube-root(16) )

The change from negative to postive  would not work  for y = c(a^x)

so...

assume   y =  a^x  + k

-2 = a^2  + k

-1 = a^5  + k

...  I would say neither..
