The First Chicago Bank is reviewing its service charges and interest-paying policies on checking accounts. The daily balance of

mrs_skeptik [129]

Answer:

The percentage of the bank's customers carry daily balances between $700 and $1,000 is 65.7%.

The minimum daily balance on which it should be willing to pay interest is $1,198.

Step-by-step explanation:

We have a normal distribution with mean = $800 and standard deviation = $150.

a) We can calculate this value with the standard normal distribution, calculating the z-value for $700 and $1,000.

$z_1=\frac{x-\mu}{\sigma} =\frac{700-800}{150}= \frac{-100}{150} =-0.67\\\\\\z_2=\frac{1,000-800}{150}=\frac{200}{150}=1.33\\\\\\P(700$

The percentage of the bank's customers carry daily balances between $700 and $1,000 is 65.7%.

b) We must calculate from what amount only 6% of the accounts remain.

This is done by solving:

$P(z>x)=0.06$

This happens for a z-value of z=2.652.

This corresponds to a amount of $1,198.

$x=\mu+z*\sigma=800+2.652*150=800+398=1,198$

The minimum daily balance on which it should be willing to pay interest is $1,198.

A recipe calls for 120 mL of milk for each 200 g of flour.Juan is going to use 1 pound of flour. Estimate the number cups of mil

Ratling [72]

Answer:

<u>1 cup</u> of milk Juan should use.

Step-by-step explanation:

Given:

A recipe calls for 120 ml of milk for each 200 g of flour.

Juan is going to use 1 pound of flour.

Now, to estimate the number of cups of milk.

Let the quantity of milk be $x.$

Now, to convert the pound of flour to gram.

1 pound = 453.59 g.

So, Juan is going to use 453.59 g of flour.

As, given recipe calls for 120 ml of milk for each 200 g of flour.

So, 120 ml is equivalent to 200 g.

Thus, $x$ is equivalent to 453.59 g.

Now, to solve by using cross multiplication method:

$\frac{120}{200} =\frac{x}{453.59}$

By cross multiplying we get:

$54430.8=200x$

Dividing both sides by 200 we get:

$272.154=x$

$x=272.154$

The quantity of milk = 272.154 ml.

Now, converting the quantity into cups by conversion factor:

1 ml = 0.004 cup.

So, 272.154 ml of milk is:

272.154 × 0.004

=1.088 cups.

Estimating the number = 1 cup.

Therefore, 1 cup of milk Juan should use.

The ________ can be a misleading measure of central tendency if the distribution of scores is ________ . A.mean; B.skewed median

LenaWriter [7]

Answer:

C) Mean, Skewed.

Step-by-step explanation:

The mean is easily influenced by outliers in a distribution. So if a Distribution of scores is skewed, then it will mislead the readers. In a skew distribution, either positive or negative, the Median will turn to be the central value. Usually, the mean is used besides other statistical parameters.

In a Normal distribution, the mean is right in the middle, symmetrically dividing the "bell shape" curve. The Mean, in this case, coincides with the mode, and the Median.

On the other hand, the Median is way more trustable central tendency measure, more resistant to outliers. So in a Skewed distribution, a Median is preferred over the Mean and use alongside the Mode.
