I am having trouble understanding this: Sam bought 86 pounds of flour for his bakery. Every day he used the same amount of flour

oksano4ka [1.4K]

Answer:

the average amount of flour used each day=6.08 pounds

Step-by-step explanation:

Sam bought 86 pounds of flour for his bakery.

Every day he used the same amount of flour to make bakery items.

After 10 days, Sam was left with 25.2 pounds of flour.

Now we are asked to find the average pounds of flour that Sam used each day.

Total amount of flour used=86-25.2=60.8 pounds.

As he used the flour equal amount each day for 10 days.

So, the average flour used each day=

amount of flour used/ number of days=60.8/10=6.08.

the average amount of flour used each day=6.08 pounds

Suppose that in a random selection of 100 colored candies, 26% of them are blue. The candy company claims that the percentage

quester [9]

Answer: a) -0.2252, b) 0.8219

Step-by-step explanation:

Since we have given that

Sample size n = 100

Probability that candies are blue = p= 0.26

Probability that company claims that it is blue candy = P = 0.27

So, Q = 1-P= 1-0.27 = 0.73

So, Null hypothesis : $H_0:p=P$

Alternate hypothesis : $H_1:p\neq P$

So, the test statistic would be

$z=\dfrac{p-P}{\sqrt{\dfrac{P.Q}{n}}}\\\\z=\dfrac{0.26-0.27}{\sqrt{\dfrac{0.27\times 0.73}{100}}}\\\\z=-0.2252$

Since α = 0.05

So, critical value of z = 1.96

p-value = P(Z>Z(calculated)

Using the excel function , we get that

$P(z>0.2252)\\\\=2\times 0.410.911845\\\\=0.8219$

Hence, a) -0.2252, b) 0.8219
