A bank report looks at what strategies and measures financial institutions are pursuing to provide mobile financial services to their customers. In a response to a survey question about barriers hindering greater consumer adoption of mobile banking, in a survey of 119 financial institutions, 78 said security concerns are a barrier, 70 said lack of trust in the technology is a barrier, and 19 said difficulty of use was a barrier. Complete parts (a) through (d) below. a. Construct a 90% confidence interval estimate of the population proportion of financial institutions who said that security concerns are a barrier hindering greater consumer adoption of mobile banking. 0.583 ≤x≤ 0.727 (Round to three decimal places as needed.) b. Construct a 90% confidence interval estimate of the population proportion of financial institutions who said that lack of trust is a barrier hindering greater consumer adoption of mobile banking. 0.514 ≤x≤ 0.664 (Round to three decimal places as needed.) c. Construct a 90% confidence interval estimate of the population proportion of financial institutions who said that difficulty of use is a barrier hindering greater consumer adoption of mobile banking. STS (Round to three decimal places as needed.)

Transcribed Image Text:A bank report examines strategies and measures that financial institutions are using to provide mobile financial services to customers. The report includes a survey about barriers hindering consumer adoption of mobile banking, with responses from 119 financial institutions. According to the survey, 78 reported that security concerns are a barrier, 70 indicated a lack of trust in the technology is a barrier, and 19 said that difficulty of use is a barrier. The task is to complete parts (a) through (c) below.
**a. Security Concerns Barrier:**
Construct a 90% confidence interval estimate of the population proportion of financial institutions indicating that security concerns are a barrier to greater consumer adoption of mobile banking.
- Confidence Interval: \(0.583 \leq \pi \leq 0.727\)
- The interval is rounded to three decimal places as needed.
**b. Lack of Trust Barrier:**
Construct a 90% confidence interval estimate of the population proportion of financial institutions indicating that a lack of trust in technology is a barrier to greater consumer adoption of mobile banking.
- Confidence Interval: \(0.514 \leq \pi \leq 0.664\)
- The interval is rounded to three decimal places as needed.
**c. Difficulty of Use Barrier:**
Construct a 90% confidence interval estimate of the population proportion of financial institutions indicating that difficulty of use is a barrier to greater consumer adoption of mobile banking.
- Confidence Interval: \(\ \_\ \leq \pi \leq \_\ \)
- The values are to be rounded to three decimal places as needed.
These confidence intervals provide an estimate of the true proportion of financial institutions perceiving each respective barrier among a wider population, based on the survey results.
