A quality control engineer at a potato chip company tests the bag filling machine by weighing bags of potato chips. Not every ba
Ahat [919]

Answer:

z=\frac{0.21 -0.15}{\sqrt{\frac{0.15(1-0.15)}{100}}}=1.68  

Step-by-step explanation:

Information provided

n=100 represent the random sample taken

X=21 represent the number of bags overfilled

\hat p=\frac{21}{100}=0.21 estimated proportion of overfilled bags

p_o=0.15 is the value that we want to test

z would represent the statistic

Hypothesis

We need to conduct a hypothesis in order to test if the true proportion of overfilled bags is higher than 0.15.:  

Null hypothesis:p =0.7  

Alternative hypothesis:p > 0.15  

The statistic for this case is:

z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}} (1)  

And replacing the info given we got:

z=\frac{0.21 -0.15}{\sqrt{\frac{0.15(1-0.15)}{100}}}=1.68

IceJOKER [234]

Answer:

  -62

Step-by-step explanation:

  -2 + (6)(-10) = -2 -60 = -62

__

2 less than a product is 2 subtracted from the product, or -2 added to the product. A product is formed by multiplying the given numbers.

The product of 6 and -10 is 6×(-10) = -60. 2 less than that is -62.

David and Jillian are playing a boardgame together Jillian wants to trade her wool cards for David ore cards the double number l
Cloud [144]

Answer:

Step-by-step explanation:

Given that:

Jillian is willing to trade her wool cards for David ore cards

The double number line indicates that:

David will trade three ore cards to Jillian for six wool cards;

Based on the ratio, we have:

= \dfrac{6}{3}

= 2

Thus, the number of wool Jillian would need to trade for 1 ore card will be

= 1 × 2

= 2

For 2 ore card

= 2 × 2

= 4

For 3 ore card

= 3  × 2

= 6

The number of wool Jillian would need to trade for 4 ore card will be

= 4 × 2

= 8
