Solution :

Median weight of a checked bag is= 27.5 pounds

it means , if there are n bags , the middlemost bag has weight 27. 5 pounds.

For , a data set, if it is symmetrical on both sides that is if difference between two succeeding values are same,then

Median = Mean

Otherwise , in some cases

Either, Median > Mean or Mean > Median.

Supposing each bag to be Equivalent, that is if they have equal weight,

Mean can't exceed ≥ 27.5 Pounds

Option B : The mean is most likely exactly 27.5 pounds,  is true about the given statement The median weight of a checked bag is 27.5 pounds.

To answer the problem above, we need first to know what median and mean means. In statistics median is the middle of the listed value data, while mean is the average of all the value of listed data. Both are kinds of averages so the mean is most like about 28 pounds.

Suppose you are conducting a test of significance to try to determine whether your cat, Hope, will go to the correct object (out
ohaa [14]

In this scenario, the parameter is the sample proportion, which is of 0.7.

<h3>What is the parameter?</h3>
  • When a hypothesis is tested, the parameter is the information obtained from the sample, mean or proportion.
  • In this case, it is the <em>sample proportion</em>, which is the <u>number of desired outcomes divided by the number of total outcomes</u>.

She goes to the correct object in 70 of those 100 trials, hence:

p = \frac{70}{100} = 0.7

The parameter is the sample proportion, which is of 0.7.

. When the last 3 digits of a year (such as
Nataliya [291]

Answer:

A ; 23rd century

Step-by-step explanation:

Here, we want to select which of the options is next to have a descending year.

Since all are in the same century i.e 20-something, we do not have an issue with the first digit.

What we need to work on is the last three digits;

We can have 2210, we can have 2321, we can have 2432, we can also have 2543 and so on.

The most recent of all these is the year 2210, so what century does this belong?

Kindly note that, the years 2001-2100 belong to the 21st century.

The years 2101-2200 belong to the 22nd century while the years 2201-2300 belong to the 23rd century

The year we are looking to place is the year 2201 and thus belongs to between 2201-2300 which is the 23rd century

What is the sum of all positive integers less than 300 which are divisible by 3
drek231 [11]

Answer:

14,850

Step-by-step explanation:

You need the sum of

3 + 6 + 9 + 12 + ... + 294 + 297

Factor out a 3 from the sum

3 + 6 + 9 + 12 + ... + 294 + 297 = 3(1 + 2 + 3 + 4 + ... + 98 + 99)

You need to add all integers from 1 to 99 and multiply by 3.

The sum of all consecutive integers from 1 to n is:

[n(n + 1)]/2

The sum of all consecutive integers from 1 to 99 is

[99(99 + 1)]/2

The sum you need is 3 * [99(99 + 1)]/2

3 + 6 + 9 + 12 + ... + 294 + 297 =

= 3 * [99(99 + 1)]/2

= 3 * [99(100)]/2

= 3 * 9900/2

= 14,850
