A national survey of companies included a question that asked whether the company had at least one bilingual telephone operator.
nirvana33 [79]

Answer:

The first option is correct. Option A is correct.

LCL = 0.270, and UCL = 0.397

80% Confidence interval = (0.270, 0.397)

Step-by-step explanation:

The data for Y and N for the 90 companies is attached to this solution provided.

Y represents companies with at least 1 bilingual operator and N represents companies with no bilingual operator.

The number of Y in the data = 30

Hence, sample proportion of companies with at least one bilingual operator = (30/90) = 0.3333

Confidence Interval for the population proportion is basically an interval of range of values where the true population proportion can be found with a certain level of confidence.

Mathematically,

Confidence Interval = (Sample proportion) ± (Margin of error)

Sample proportion = 0.3333

Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error)

Critical value at 80% confidence level for sample size of 90 is obtained from the z-tables.

Critical value = 1.280

Standard error of the mean = σₓ = √[p(1-p)/n]

p = sample proportion

n = sample size = 90

σₓ = √[0.3333×0.6667)/90] = 0.0496891568 = 0.04969

80% Confidence Interval = (Sample proportion) ± [(Critical value) × (standard Error)]

CI = 0.3333 ± (1.28 × 0.04969)

CI = 0.3333 ± 0.0636021207

80% CI = (0.2696978793, 0.3969021207)

80% Confidence interval = (0.270, 0.397)

Hope this Helps!!!

Another payment type enabled by smartphones is person-to-person payments, which are apps that allow people to send money electro
Galina-37 [17]

Answer and Step-by-step explanation:

Person to person payment is an online technology that allows customers to transfer their money and funds from their account to another account through mobile phones. A p2p app allows one user to send money to another user by using an app or website—transaction including anything from paying a dinner bill, rent, or contributing to charity.

The increased obtaining of online banking, mobile banking, and e-commerce by users has paved the way for greater use of person-to-person payments. In the payment markets sending money between smartphones has become an ordinary matter. According to Billtrust, young adults are using a person to person payment more than two generations.

Nearly half of smartphone owners regularly used p2p payment apps. Most people used p2p payment app because it offers better security or most of their peers use it.

Millennials have often led older Americans in their adoption and use of technology. More than 93% millennial (who turns ages 23 to 38 this year) have their smartphones. Similarly, the vast majority of millennials use social media, compared with smaller shares among old generations.

Solve for t. (Answer must be completely simplified)<br> 10t=11
AlexFokin [52]

Answer:

T can be equal to 1 1/10 or 1.1 or 11/10

Step-by-step explanation:

10t=11

So divide by 10 on both sides.

t=11/10 which can be simplified to t=1 1/10 or t=1.1
