According to statcounter, Google Chrome browser controls 62.8% of the market share worldwide. A random sample of 70 users was selected. What is the probability that 35 or more from this sample used Google Chrome as their browser

The probability that 35 or more from this sample used Google Chrome as their browser is 0.9838.

Step-by-step explanation:

We are given that according to Statcounter, the Google Chrome browser controls 62.8% of the market share worldwide.

A random sample of 70 users was selected.

Let = sample proportion of users who used Google Chrome as their browser.

The z-score probability distribution for the sample proportion is given by;

                              Z  =    ~ N(0,1)

where, = sample proportion = = 0.50

            p = population proportion = 62.8%

            n = sample of users = 70

Now, the probability that 35 or more from this sample used Google Chrome as their browser is given by = P( 0.50)

       P( 0.50) = P( ) = P(Z -2.14)

                           = P(Z 2.14)  = 0.9838

The above probability is calculated by looking at the value of x = 2.14 in the z table which has an area of 0.9838.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
