You roll two dice. Let event A be "The first die shows a 2,a 3, or a 5" and event B be "The second die shows an odd number." Wha

t is P(A/B)?
Write fractions using the slash ( / ) key. Reduce fractions to their lowest terms.

( The / is supposed to be the straight line but I didn't know how to put it on here.)

P(A) = 3/6 (3 out of all possible outcomes) = 1/3
P(B) = 3/6 = 1/3 again since possible odd numbers are 3 (1,3,5)
P(A/B) is basically 1/3 / 1/3
which is (3/3 = ) 1

Haven't worked with possibilities in ages so I'm not sure for the P(A/B) part! Sorry!

.A variety of stores offer loyalty programs. Participating shoppers swipe a bar-coded tag at the register when checking out and
Leni [432]

Answer:

a) Null hypothesis:\mu \leq 120  

Alternative hypothesis:\mu > 120  

b) t=\frac{130-120}{\frac{40}{\sqrt{80}}}=2.236  

The degrees of freedom are given by:

df = n-1 = 80-1=79

The p value for this case taking in count the alternative hypothesis would be:

p_v =P(t_{79}>2.236)=0.0141  

Step-by-step explanation:

Information given

\bar X=130 represent the sample mean for the amount spent each shopper

s=40 represent the sample standard deviation

n=80 sample size  

\mu_o =120 represent the value to verify

t would represent the statistic    

p_v represent the p value f

Part a

We want to verify if the shoppers participating in the loyalty program spent more on average than typical shoppers, the system of hypothesis would be:  

Null hypothesis:\mu \leq 120  

Alternative hypothesis:\mu > 120  

The statistic for this case would be given by:

t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}} (1)  

Replacing the info given we got:

t=\frac{130-120}{\frac{40}{\sqrt{80}}}=2.236  

The degrees of freedom are given by:

df = n-1 = 80-1=79

The p value for this case taking in count the alternative hypothesis would be:

p_v =P(t_{79}>2.236)=0.0141

25 cm of ribbon at £2.20 per metre what is the cost

0.55 pence or quid per 25 centimeters as if you multiply it by 4 it would be 2.20 pound because 1 metre is 100 centimeters after i divide 100 by 25 i get 4 which would be 1/4 which i would then multiply 1/4 x 2.2 pound
