Calculate F statistic for the following. If SSB = 15.62 (dfb =4) and SSW = 6.39 (dfw = 16)

It is thought that prehistoric Indians did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps. It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) of an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation. The following data were obtained for a collection of archaeological sites in New Mexico. x 5.23 5.89 6.25 6.75 7.25 y 18 11 33 37 62 Complete parts (a) through (e), given Σx = 31.37, Σy = 161, Σx2 = 199.2325, Σy2 = 6747, Σxy = 1064.43, and r ≈ 0.884.  (b) Verify the given sums Σx, Σy, Σx2, Σy2, Σxy, and the value of the sample correlation coefficient r. (Round your value for r to three decimal places.) Σx =   Σy =   Σx2 =   Σy2 =   Σxy =   r =…

A survey of 700 non fatal accidents showed that 287 involved defective equipment.  Find a point estimate for p, the population proportion of accidents that involved defective equipment and round to 4 decimal places if needed.

A large automobile insurance company selected samples of single and married male policyholders and recorded the number who made an insurance claim over the preceding three-year period. Z-value p-value Single Policyholders n₁ = 440 Number making claims = 88 a. Use a = 0.05. Test to determine whether the claim rates differ between single and married male policyholders. (to 2 decimals) (to 4 decimals) X Married Policyholders n2 = 840 Number making claims 126 We can conclude ✔ that there is the difference between claim rates. b. Provide a 95% confidence interval (to 4 decimals) for the difference between the proportions for the two populations. Enter negative answer as negative number. X * )

A sample of 150 married women determined that 127 are happy in their marriage. A sample of 150 married men determined that 76% are happy in their marriage.   If you plan to test if the percent of married women who are happy in their marriage is greater then the percent of married men who are happy in their marriage- Answer the following: What is the test statistic? Write to 4 decimal places.

Let's assume that your friend is transferring to a four-year institution with a 3.6 GPA and 60 credit hours. During the first year at the new college, your friend takes 30 credits and earns a 2.8 GPA. Use the following processes to help your friend determine their overall GPA (combining the community college and four-year university credits). First, follow the steps below to use the weighted average method to find your friend's combined GPA. Part A: How many total points were earned at the community college? 216 Part B: How many total points were earned at the four-year institution? 84 o points 300 Part C: How many total points were earned at the two institutions? ✓opoints. 90 o points Part D: What is the total number of credit hours successfully completed at the two institutions? o total credit hours.
