Question

Let p = 0.3 be the proportion of smart phone owners who have a given app. For a particular smart phone owner, let x = 1 if they have the app and x = 0 otherwise. For a random sample of 40 owners, complete parts a through e below. a. State the population distribution (that is, the probability distribution of X for each observation). P(X=1)= 0.3 and P(X = 0) = 0.7 (Type integers or decimals. Do not round.) b. State the data distribution if 24 of the 40 owners sampled have the app. (That is, give the sample proportions of observed Os and 1s in the sample.) The proportion for x = 1 is and the proportion for x = 0 is (Type integers or decimals. Do not round.)

7.4 iPhone apps Let p = 0.25 be the proportion of iPhone owners who have a given app. For a particular iPhone owner, let x = 1 if they have the app and x = 0 otherwise. For a random sample of 50 owners: a. State the population distribution (that is, the probability distribution of X for each observation). b. State the data distribution if 30 of the 50 owners sampled have the app. (That is, give the sample proportions of observed 0s and 1s in the sample.) c. Find the mean of the sampling distribution of the sample proportion who have the app among the 50 people. d. Find the standard deviation of the sampling distribution of the sample proportion who have the app among the 50 people. e. Explain what the standard deviation in part d describes.

The proportion of adults living in a small town who are college graduates is estimated to be p = 0.3. To test this hypothesis, a random sample of 100 adults is selected. If the number of college graduates in the sample is anywhere in the fail-to-reject region defined to be 20 ≤ x ≤ 40, where x is the number of college graduates in our sample, we shall not reject the null hypothesis that p = 0.3; otherwise, we shall conclude that p ≠ 0.3. Complete parts (a) through (c) below. Use the normal approximation.

00:01 Hello, students, we are going to write here probability is equal to 0 .3 for particular smartphone owner, let x is equal to 1 if they have app x is equal to 0 otherwise.
00:11 N value is 40 owners.
00:13 So if i write here for this, in the first case, we are going to write here for this.
00:19 P value as 0 .3, we are going to write here be the proportion of proportion of, proportion of if i write here for this smartphone owners we are going to write here for this this must be written as who have who have given we are going to write here for this who has who has given we are going to write here for this app who has given we are going to write here for this from the given data from so this must be written as we are going to write here for this so we are going to write this must be written as from the given data from the given data given data this must be written as x is equal to one when the smartphone have a app a smartphone have a have a app we are going to write here for this this must be written as x is equal to zero or when x is equal to zero when the smartphone, so let's erase this to make it more clear, smartphone, if i write here for this, this must be written as don't have a app, do not have a app.
02:18 We are going to write here for this, this must be written as.
02:22 So finally in the a part we can write here probability of x value is equal to 1 which is 0 .3.
02:31 We are going to write here for this.
02:34 This must be 0 .3.
02:36 And if i write here what would be probability of x is equal to 0? this is 1 minus 0 .3 which is 0 .7.
02:45 So probability of x values equal to 0 is 0 .7.
02:49 And if i write here, we are going to write here for this...
