Question

distributed Use a t-test to test the claim about the population mean ji at the given level of significance a using the given sample statistics. Assume the population is normally Claim: #26; a=0.10 Sample statistics: X = 26.5, s=4.3, n = 11 What are the null and alternative hypotheses? Choose the correct answer below O A. Ho +26 OB. Ho: 226 H, = 26 H <26 OCH p=26 OD. HY S 26 H, #26 H>26 What is the value of the standardized test statistic? The standardized test statistic is (Round to two decimal places as needed) What is the P-value of the test statistic? P-value = (Round to three decimal places as needed.)

Answer 1

Here we have: X = 26.5 S = 4.3 n = 11 a = 0.10 Hypothesis: Correct option "C" Hoi u = 26 Hai ! # 26 Test statistics: t-distribution (o unknown) χ-μ t = 26.5-26 4.3 V11 = 0.39 in

df = n-1 = 11 -1 = 10 P-value = 2p (t>|0.391) = 0.705 Correct option "B" Fail to reject Ho. There is not enough evidence to support the claim

Answer 2

The 24 consonant sounds comprise six stops (plosives): p, b, t, d, k, g; the fricatives f, v, θ (as in thin), ð [eth] (as in then), s, z, ∫ [esh] (as in ship), Ʒ (as in pleasure), and h; two affricatives: t∫ (as in church) and dƷ (as the j in jam); the nasals m, n, ŋ (the sound that occurs at the end of words such as young); the lateral l; the postalveolar or retroflex r; and the semivowels j (often spelled y) and w. These remain fairly stable, but Inland Northern American differs from RP in two respects: (1) r following vowels is preserved in words such as door, flower, and harmony, whereas it is lost in RP; (2) t between vowels is voiced, so that metal and matter sound very much like British medal and madder, although the pronunciation of this t is softer and less aspirated, or breathy, than the d of British English.
