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 7/9 times 21/28 as a simplified fraction
Serga [27]

Answer: 7/12!

Step-by-step explanation: 7/9 times 21/28 = 147/252. But you have to reduce it (simplify it) by dividing both the numerator and denominator by the greatest common factor and you get 7/12! Hope this helped.

List 2 integers that are congruent to 4 modulo 14.
vivado [14]

Answer:

32, 46

Step-by-step explanation:

Remember, a is congruent to b modulo d if d divides a-b.

Now, the problem says that b=4 and d=14.

Let a=32. Observe that a-b=28 and \frac{28}{14}=2, then 32 is congruent to 4 modulo 14.

Let a=46. Observe that a-b=46-4=42 and \frac{42}{14}=3, then 46 is congruent to 4 modulo 14.

WILL GIVE BRAINLIEST: If the graph of 2x+3y − 6=0 is perpendicular to the graph of ax − 3y=5. What is the value of a?
Ilya [14]

Answer:

a = \frac{9}{2}

Step-by-step explanation:

To find the value of a, find the Slope of both the equations.

For lines to be perpendicular to each other    m_{1}m_{2}  = - 1

For line 1:

2x + 3y − 6 = 0 represent the line in y=mx +c form

3y = -2x + 6

y = \frac{-2}{3} x + \frac{6}{3}

y = \frac{-2}{3} x + 2

m_{1} = \frac{-2}{3}

For line 2:

ax - 3y = 5

ax = 5 + 3y

ax - 5 = 3y

y = \frac{ax}{3} - \frac{5}{3}

m_{2} = \frac{a}{3}

Apply the condition of perpendicularity:

\frac{-2}{3} * \frac{a}{3} = - 1

\frac{2a}{9} = 1

a = \frac{9}{2}

A plumber and a builder were employed to fit a new bath, each working a different number of hours. The plumber earns 35 per hour
san4es73 [151]

Answer:

The builder worked roughly 12 hours and the plumber worked around 13. The builder got paid 330.75 so just divide 28 by that to get 11.9... then add 330.75 and 106.75 (which will be 437.50) and divide the sum by 35 the get 12.5.
