A new WiFi range booster is being offered to consumers. A researcher tests the native range of 12 different routers under the same conditions. The ranges are recorded. Then the researcher uses the new WiFi range booster and records the new ranges. Does the new WiFi range booster do a better job?

Short Answer

Expert verified

Thus, Matched or paired samples.

Step by step solution

01

Given information

Consumers can now purchase a new WiFi range extender. Under the same settings, a researcher evaluates the native range of 12 different routers.

02

Indicate if the hypothesis test and does the new WiFi range booster do a better job.

Letμd be the mean difference between the native and WiFi range enhancer ranges.

The statement's null and alternative hypotheses are as follows:

Ho:μd=0H1:μd>0

As a result, matching or paired samples are used.

Varsity athletes practice five times a week, on average.

Two types of phone operating system are being tested to determine

if there is a difference in the proportions of system failures (crashes). Fifteen out of a random sample of 150 phones with OS1had system failures within the first eight hours of operation. Nine out of another random sample of 150 phones with OS2had system failures within the first eight hours of operation. OS2is believed to be more stable (have fewer crashes) than OS1.

What can you conclude about the two operating systems?

Five ball players think they can throw the same distance with their dominant hand (throwing) and off-hand (catching hand). The data were collected and recorded in the table given below. Conduct a hypothesis test to determine whether the mean difference in distances between the dominant and off-hand is significant. Test at the 5%level.

Calculate the test statistic and p-value.

What can you conclude about the two operating systems?
