Open Question: 10 points help
While a mother
While a mother comforts her teething 8.5-month-old child, she begins to wonder when the baby’s first tooth will come. After all, the screaming has to stop some time.
Based on the mean age of a child’s first tooth is 0.629 years and the standard deviation is 0.154 years, the Range Rule of Thumb shows us that this is clearly NOT unusual (Statistics courtesy of Holly Smith, Tracey Crummett, and Kari Brandt of The University of Michigan’s study Ages of Eruption of Primate Teeth, 1994). 8.5 months is within one standard deviation of the mean, let alone two. However, the father of the baby has taken statistics. He determines that the probability of a child cutting their first tooth at 8.5 months or later is about 30%. The mother exclaims, “Our child is in the minority! Something is wrong. This is unusual.”
Either the Range Rule of Thumb is incorrect, or the mother’s reasoning is incorrect. Which is incorrect, and why?

Resolved Question: Your child with autism.
Your child with Autism. vaccines?
If you could shed some light and experiences, it would be greatly appreciated. My child is due for his MMR vaccine soon. To be honest, I'm terrified. I've read so many articles from experts in the medical field, although supposedly debunked, I'm still unsure about this shot. I've also read articles and forums where parents were convinced with absolute certainty that the mmr was the root cause of their child developing autism. I even read one forum when her daughter was given the shot at age 2 (she was walking and talking) and suddenly stopped. That's a pretty convincing story since at age 2, you could pretty clearly tell whether your child is developing properly. My question is: do you think there is a direct link between the mmR and your child being on the spectrum? Is it vaccines in general and your Childs genetic composition that just couldn't tolerate certain vaccines? Also, did you breastfeed?? Many people are blaming the lack of mothers not breastfeeding being a cause to the vulnerability to toxins in these vaccines. Please enlighten me & share your experiences. Thank you!!!
