Use the random sample data to test the claim that less than 29% of local residents have access to high speed internet at home. Use 1% level of significance. Sample data: x = 45, n = 200 Identify the tail of the test.                             [ Select ]                       ["Two tail test", "Left tail test", "None of these", "Not enough information", "Right tail test"]       Find the P-value                             [ Select ]                       ["0.0523", "0.0214", "0.0209", "None of these", "0.0279"]       Will the null hypothesis be rejected?                             [ Select ]                       ["It depends", "Fail to reject H0", "Not enough information", "Reject H0", "None of these"]       Is the initial claim supported?                             [ Select ]                       ["None of these", "The claim is supported", "Not enough information", "The claim is not supported", "It depends"]

(b) Compute the value of the test statistic. Round the answer to at least three decimal places.

Solve for B which reads assume prior studies have shown that about 45% of full-time students are in bachelors degree and four years or less. n=

Solve for C

Below indicate whether the appropriate test would be an independent t-test, dependent t-test, One-way ANOVA, or z-test. A researcher wants to know if people find baby animals cuter than adult animals. All of the participants in a study are shown 10 pictures of baby animals and 10 pictures of adult animals. They are asked to rate (on a 1 to 10 scale) how cute they think each animal is.

This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used.  0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean.  0.5 point for finding the correct probability.   All work must be shown in order to receive any credit.  Please upload your completed assignment here.    The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard deviation of 0.25 hours. A sample size of n = 60 is drawn randomly from the population. Find the probability that the sample mean is between two hours and three hours.

Two computer users were discussing tablet computers. A higher proportion of people ages 16 to 29 use tablets than the proportion of people age 30 and older. The table below details the number of tablet owners for each age group. Test at the 1% level of significance. (For subscripts let 1 = 16-29 year old users, and 2 = 30 years old and older users.)   16–29 year olds 30 years old and older Own a Tablet 69 231 Sample Size 625 2,313 NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) Part (a) State the null hypothesis. H0: p1 < p2 H0: p1 > p2      H0: p1 ≠ p2 H0: p1 = p2 H0: p1 ≥ p2 Part (b) State the alternative hypothesis.
