Question

One of the most​ impressive, innovative advances in online fundraising over the past decade is the rise of​ crowd-funding websites. While features differ from site to​ site, crowd-funding sites are websites that allow you to set up an online fundraising campaign based around a fundraising​ page, and accept money directly from that page using the​ website's own credit card processor. A certain​ crowd-funding website reported that 131 of 357 technology​ crowd-funding projects were successfully launched in the past year and 345 of 872 film and video​ crowd-funding projects were successfully launched in the past year. 

State the conclusion

 

State the conclusion. the null hypothesis. There is evidence to support the claim that there is a significant difference in the proportion of successful technology crowd-funding projects and successful film and video crowd-funding projects.

The probability of obtaining a difference in proportions that gives rise to a test statistic the V is equal to the p-value of if there is no difference between the population proportions of successful technology crowd-funding projects and successful film and video crowd-funding projects. (Type an integer or a decimal. Round to three decimal places as needed.) c. Construct and interpret a 99% confidence interval estimate for the difference between the proportion of technology crowd-funding projects and film and video crowd-funding projects that are successful. The researchers performing this study can be V confident that the difference in the population proportion of successful technology crowd-funding projects and successful film and video crowd-funding projects is the interval from to . (Type integers or decimals. Round to four decimal places as needed.)
