Annie is concerned over a report that "a woman over age 40 has a better chance of being killed by a terrorist than of getting married." A study found that the likelihood of marriage for a never- previously-wed, 40 -year-old university-educated American woman was 3.3% . To demonstrate that this percentage is too small, Annie uses her resources at the Baltimore Sun to conduct a simple random sample of 454 never-previously-wed, university-educated, American women who were single at the beginning of their 40 s and who are now 45 . Of these women, 21 report now being married. Does this evidence support Annies claim, at the 0.10 level of significance, that the chances of getting married for this group is greater than 3.3% ? Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places..

ANALISIS DE CASO Mars Inc.:fusin de las divisiones europeas de alimentos, cuidado de mascotas y confitera Mars Inc. es una empresa multifuncional diversificada cuyos productos principales incluyen alimentos, cuidado de mascotas, confitera, productos electrnicos y bebidas. Propiedad y control de la familia Mars, este gigante estadounidense es una de las empresas privadas ms grandes del mundo, pero tambin una de las ms reservadas. La decisin de Mars en enero de 2000 de fusionar sus divisiones de alimentos, cuidado de mascotas y confitera en toda Europa, y finalmente con la sede en el Reino Unido, ha dividido la industria del marketing. Las marcas ms conocidas dentro de las tres divisiones son: Mars UK dice que la decisin de agrupar los negocios se tom para atacar a los competidores internacionales de la compaa en alimentos y confitera, como Nestl y Unilever. La medida tambin coincide con los planes para crear un mercado europeo nico y destaca la creencia de la empresa de que las necesidades de sus consumidores son las mismas en todo el continente. Sin embargo, la combinacin de alimentos y dulces con el cuidado de mascotas no est clara para todos los observadores de la industria. Un analista de la industria hizo el comentario: En trminos generales, Mars est haciendo lo correcto al fusionar divisiones para sacarles ganancias. Antes de la llegada del euro, era aceptable dirigir empresas separadas en diferentes pases europeos, pero ya no. Otro analista dijo: 'No puedo imaginarlo comercializando los tres lados del negocio juntos. Son demasiado diferentes. El nico beneficio visible parece ser una mejora en la distribucin. Los gustos en los mercados europeos son muy diferentes, ya sea que est vendiendo productos para animales o personas. Est muy bien que Mars diga que se enfrentar a competidores como Nestl y Unilever, pero solo son rivales en alimentos y confitera. Si Mars comienza a establecer demasiados controles al fusionar todos sus negocios, y por lo tanto tambin sus estrategias de marketing y gestin, puede optimizar las comunicaciones, pero podra perder la creatividad disponible en diferentes regiones. Preguntas: 1. Discutir los dos puntos de vista de la organizacin de las actividades europeas de Mars. (100 palabras) 2. Mars Inc. hizo lo correcto en su opinin? (100 palabras).

An unusual problem has occurred for a small multinational company: People are getting confused about dates in internal memos, purchase orders, and email. When the companys database was originally designed, the designer was not aware that the format for dates in Canada and Mexico was different from the format used in the United States. For example, in Canada and Mexico, the notation 7/1/19 indicates January 7, 2019, whereas in the United States the same notation indicates July 1, 2019. Although it seems like a small point, the date confusion has resulted in several order cancellations. How would you fix this issue in the database?.
