Write the null and alternative hypothesis and identify which is the claim for each of the following:
1. The proportion of electronic circuits that operate properly is more than 95%
2. the mean length of time a mother board lasts is 2.3 years.
Homework Answers
solution:
This is the right tailed test .
The null and alternative hypothesis is
H0 : p =0.95
Ha : p > 0.95
2.
this is the right tailed test .
The null and alternative hypothesis is ,
H0 : 
= 2.3
Ha :
> 2.3

Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Among 2031 passenger cars in a particular region, 227 had only rear license plates. Among 300 commercial trucks, 45 had only rear license plates. A reasonable hypothesis is that commercial trucks owners violate laws requiring front license plates at a higher rate than owners of passenger cars....
