The following data represent the pH of rain for a random sample of 12 rain dates. a normal probability plot suggest the data cou
babunello [35]

Answer:

Step-by-step explanation:

a) Estimate for population mean = Sum/n =\frac{59.1}{12} =4.925

b) Variance = 0.099208

Std dev = 0.314974

Std error = 0.0950

For 95% margin of error = 1.96*Std error

=0.1861

Confidence interval = (4.925-0.1861, 4.925+0.1861)\\=(4.7389, 5.1111)

Interpretation of confidence interval:

A) if repeated samoles are taken, 95% of them will have a sample pH of rain water between [ ] & [ ].

For 99%  CI,  z value = 2.59

Conf interval = (4.6790, 5.1710)

C)if repeated samoles are taken, 99% of them will have a sample pH of rain water between [ ] & [ ].

As the level of confidence increases l, the width of the interval[ increases] this makes sense since the [  margin of error] [increases]

It cost abigail $3.68 to send 92 text messages. how much does it cost to send one text?
iogann1982 [59]

It costs around $0.04 to send one text message.

Using unitary method, the cost of sending 92 text messages = $3.68

hence the cost of sending one text message = \frac {3.68}{92} = 0.04

the cost for sending one text message is 0.04.

<h3>What is text message?</h3>
  • Text messaging, or texting, is the act of composing and sending electronic messages, typically consisting of alphabetic and numeric characters, between two or more users of mobile devices, desktops/laptops, or another type of compatible computer.
  • Text messages may be sent over a cellular network, or may also be sent via an Internet connection.
  • The term originally referred to messages sent using the Short Message Service (SMS). It has grown beyond alphanumeric text to include multimedia messages using the Multimedia Messaging Service (MMS) containing digital images, videos, and sound content, as well as ideograms known as emoji (happy faces, sad faces, and other icons), and instant messenger applications (usually the term is used when on mobile devices).
