Question

This Test: 40 pts possible said "one." 361 said "two," 144 said "three," and 82 responded with four or more A survey respondent is selected household to have four or more cell phones in use? Consider an event to be unlikely if its probability is less than or equal to were asked how many cell phones were in use by the household (No two respondents were from the same household ) Among the respondents, 206 anawored "none, "298 with four or more A survey respondent is selected at random. Find the probability that his/her househoild has four or more cell phones in use is it unikely for a 0 05 Ptfour or more cell phones)- Round to three decimal places as needed ) Is it unlikely for a household to have four or more cell phones in use? O A. No, because the probability of a respondent with four or more cell phones in use is greater than 0.05 B. Yes, because the probability of a respondent with four or more cell phones in use is greater than 005 C. Yes, because the probability of a respondent with four or more cell phones in use is less than or equal to 0 05 D. No, because the probability of a respondent with four or more cel phones n use is less than or equal to o os.

Explanation / Answer

here total number =206+298+361+144+82=1091

hence P(4 or more) =82/1091=0.075

option A is correct

2)please see if this values are right if not revert as picture is blurry

putting above in ascending order:

a) mean =240.2

b)median =(n+1)/2 th value=6th value =235

c)

mode =235

211 235 248 207 274 222 297 255 235 229 229
