Answer:

Your answer is B

Step-by-step explanation:

First we have to find the Y intercept, which is -2.

Then you have to find the slope. Rise/Run

If you count up 5 and left 2 you get your next point. Meaning that 5/-2 is your slope.

Suppose according to past data for a small boutique, about 30% of the customers who walk into the store purchase at least one it

sashaice [31]

Answer:

Step-by-step explanation:

Let X be the no of customers who purchase atleast one item.

X is binomial since there are two outcomes and each customer is independent of the other.

a) Here n =10

Out of 10 customers we expect np = 3 customers to buy at least one item.

b) exactly 3 of the customers would purchase at least one item

= $P(X=3)=10C3(0.3)^3(0,7)^7\\=0.2668$

c) the probability that no more than 3 customers would purchase at least one item

= $P(X\leq 3)\\= 0.6496$

1A technical magazine stated that the mean retail cost of all models of a particular laptop was $600. A random sample of 10 stor

My name is Ann [436]

Answer:

Yes

Step-by-step explanation:

Given,

Population mean Z = 600

Sample mean, µ = 586.50

Size of the sample, n = 10

Standard deviation, σ = 26.77

The testing hypothesis is,

Null hypothesis = µ<600

Alternative hypothesis = µ≥600

The test statistics is the calculated value of Z,

(Z- µ)/(σ/√n)

= (600-586.50)/(26.77/√10)

= (13.5*3.1623)/26.77

= 42.691/26.77

= 1.5947

And at 5% level of significance, the table value of Z = 1.644

Here, calculated Z<Table value of Z, so we accept the null hypothesis.

So, the null hypothesis is accepted. The mean value of the laptop is less than 600.
