Bernice estimated that 69% of 242 is 168. Is her estimate reasonable?

ycow [4]

Her estimate is not reasonable.

Since she estimated 69%, you could do either of these options. You could...
A. Divide 242 (or .5) to show how much half off would be, then compare her estimate with half of 242 (121). OR...
B. Simply divide 242 by 69% (.69) and compaor her estimate to the exact amount (166.98).

I hope this helps!

The previous exercises states that the distribution of speeds of cars traveling on the Interstate 5 Freeway (I-5) in California

mote1985 [20]

Answer:

The probability is $P(X \le 70 ) = 0.7054$

Step-by-step explanation:

From the question we are told that

The mean is $\mu = 72.6 \ miles /hour$

The standard deviation is $\sigma = 4.78 \ miles /hour$

The speed limit is $x = 70 \ miles /hour$

Generally the probability that 5 cars pass and none are speeding is equivalent to the probability that the speed of the cars is less than x which is mathematically represented as

$P(X \le x ) = 1 - P(X > x )$

Now

$P(X > x) = P(\frac{X - \mu}{\sigma } >\frac{x - \mu}{\sigma } )$

Generally

$\frac{X - \mu}{\sigma } = Z (The \ standardized \ value \ of \ X)$

So

$P(X > 70) = P(Z >\frac{70 - 72.6}{72.6 } )$

$P(X > 70) = P(Z > -0.54 )$

From the z-table

$P(Z > -0.54 ) = 0.2946$

=> $P(X > 70) = 0.2946$

So

$P(X \le 70 ) = 1 - P(X > 70 )$

=> $P(X \le 70 ) = 1 - 0.2946$

=> $P(X \le 70 ) = 0.7054$

The following lots of Commodity Z were available for sale during the year. Beginning inventory 9 units at $50 First purchase 16

GarryVolchara [31]

According to the FIFO method, the ending inventory balance for Commodity Z is $1,405

<h3>How much inventory is left under FIFO?</h3>

FIFO means that earlier inventory is sold first and later inventory would be the last goods left.

Since there were 23 units left, all 16 units from the last purchase and 7 units from the second purchase would be available:

= (16 x 62) + (7 x 59)

= 992 + 413

= $1,405

Select whether a chi-square test for association is the most appropriate for the following scenarios: Most appropriate or Not ap

Ivan

Answer:

Step-by-step explanation:

For option (A), yes.

The chi-square test for association between two categorical variables is appropriate for this.

For option (B), no.

Danielle's survey wants to HOW OFTEN people eat dinner at a restaurant. The chi-square test for association does not match this. The chi-square test for association would have been suitable if Danielle wanted to know the significance of the association between a certain type of people and a certain restaurant or food.

For option (C), no.

For option (D), yes.
