According to recent reports, Apple Inc. holds 27.6% of the Tablet Computer market. Suppose a consumer research company believes

that 27.6% is too high and undertakes a survey to see if their suspicion is supported by the sample data. A random sample was taken of tablet computer purchases and find that of 200 purchases, 52 are Apple tablet computers. The P-value is 0.3064 and the hypothesis is : H:P = 0.276 H:P < 0.276 You would conclude at a significance level of 5%.
There is statistically significant evidence that Apple Inc. holds less than 27.6% of the tablet computer market.
there is a 30.36% chance that Apple Inc. holds at least 27.6% of the Tablet computer market.

Answer:

We don't have sufficient evidence to support the claim

Step-by-step explanation:

Null hypothesis:

H_0: p = 0.276

Alternate hypothesis:

H_1: p < 0.276

The P-value is 0.3064

0.3064 probability of finding a sample proportion lower than the one found.

The p-value is higher than the significance level of 0.05, which means that there is no sufficient evidence to support the claim.

A bag contains 31 red​ blocks, 47 green​ blocks, 23 yellow​ blocks, and 24 purple blocks. You pick one block from the bag at ran
svp [43]

Answer:

0.07072

Step-by-step explanation:

Red Blocks= 31

Green Blocks= 47

Yellow blocks = 23

Purple blocks= 24

Total= 31+47+23+24= 125

P(Yellow) = 23/125

P(Purple)=24/125

NOTE: AND (X), OR (+)

​P(yellow yellow or purple purple​)

= P(Y and Y) + P(P and P)

=(23/125 X 23/125) + (24/125 X 24/125)

=529/15625 + 576/15625

=1105/15625

=221/3125

=0.07072

Therefore:

Probability of Picking Yellow Yellow or Purple Purple is 0.07072.
